Technical Corner

For the article this month I’d like to touch on tap changers that are associated with transformers.

Tap changers are typically utilized and installed on the primary of a transformer and are used to offset any higher or lower input voltages.

The theory is that if your primary voltage is not correct then the secondary voltage will not be correct either. The goal is to get that secondary voltage as close as possible to the rated voltage, otherwise, the equipment connected to it may not operate effectively.

One reason why primary voltage may fluctuate, and dip, is due to increased load connected to that transformer Another reason would be voltage drop. Our transformer might be too far away from the source that feeds it.

There is a pretty good description and calculation example for the following formula in the video link below:

Tap Percentage= (Actual Voltage-Rated Voltage)/Rated Voltage

https://www.youtube.com/watch?v=R233i5ihF88

Typical tap percentages are plus and minus 2.5% and 5%.

Some things to look for when using taps on a transformer:

FCBN-Full Capacity Below Normal

FCAN-Full Capacity Above Normal

RCBN-Reduced Capacity Below Normal

This basically means that the kVA rating of the transformer will not change when connected to one of the taps. This is normally preferred. Reducing the kVA rating of the transformer (RCBN) could introduce some other issues as it essentially reduces what the transformer can be connected to, or in other words it’s capacity.

Some types of taps are as follows:

On Load Tap Changer-OLTC-tap change completed in energized state

De-Energized Tap Changer-DETC-tap change completed in de-energized state

Hopefully this article finds you well and can be used as a reference for your project needs. If anyone would like to contribute to the Rochester Engineer and add an article or would like to request information on a specific topic (not limited to Electrical) just email Brett Eliasz at beliasz@bergmannpc.com. As always, any comments are appreciated! Thank you for reading.

RES News - Rochester History

A Sampling from the Archives of the Rochester Engineering Society. 1897 - 1976

by Lee M. Loomis

Continuing with the historical sampling of the earlier writings on behalf of the Rochester Engineering Society, the years following "The Great War", into and through the “Great Depression”, continued to be a time of reaching out for the maturing Society, both locally and nationally. The meeting minutes describe a series of technical discussions and presentations intended to broaden the technical horizons of the membership (especially the CE's, ME's and EE's). The RES affiliated itself with a number of National technical societies, adopted local Affiliated Societies, frequently held joint meetings with them and continued taking action on a growing list of public matters. Certain issues of standardization, some crucial to public safety, became the responsibility of the RES and its affiliates. In the pervasive economic downturn of the “Great Depression”, the magazine offered classified advertising for unemployed engineers, technicians and draftsmen and took other steps to try to deal with the crisis. Still, it continued its effort to shape the function, focus and infrastructure of the City of Rochester, and beyond. World War, again affected the Society, taking away many of its leaders while providing opportunities for others to step forward to fill these vacancies. In an effort to provide even greater perspective on the happenings and concerns of the day, a synopsis, featuring selected items from "The Rochester Engineer" has become an integral part of this series. The Second World War, the Korean Conflict, and the Vietnam War are now history. These experiences have changed the face of and will, no doubt, influence the future of the community. The Rochester municipal leadership and the industrial community have become immersed in the cold-war, growth economy.

March 17, 1976 (Board Meeting, Chamber of Commerce)

The Board approved application for nine Regular Memberships, two Associate Memberships, two Junior Memberships and one Student Membership. RES Treasurer, Howard Jaquith, recommended the redemption of $7,000 in Master Notes from the Kate Gleason Fund to offset the current operating deficit and anticipated future expenses. The Board approved an allocation of $50 to RES Member, Robert Freitag, in support of an RES-sponsored “Technology Contest” at the upcoming St. John Fisher College Science Exploration Days. RES Director, Richard Blazey reported success in recruiting four engineers for RES Director, George Landberg’s RES Education Committee project wherein these volunteers would be speaking to Greece Central High Students on careers in mechanical, civil, electrical and chemical engineering. President Jack Schickler reported that he had written to Rochester Mayor Thomas Ryan, declining his request for an “official” recommendation on the City’s purchase of the RG&E street lighting system. Instead, it was decided that RES Director, Ron Salzman would, at an upcoming Channel 21 program, pose a question to City Councilmen John Curran and Paul Heney, on the propriety of the City making such a purchase. RES Director, John Robertson, reported that the final three programs of the RES Luncheon series would include Monroe County Pure Waters Director, Gerald McDonald (March), Kodak office dinner and tour of Channel 21 (April), and a tour of the Strasenburgh Planetarium (May). President Schickler announced the follow slate of RES Officers and Directors: President – M. John Corson (RG&E), 1st Vice President – Dr. Douglas M. Marshall (RIT),

2nd Vice President - Elwood Dobbs (EKCo), Treasurer – John M. Robertson (Rochester Telephone), Directors – Daniel E. Turner ’78 (General Railway Signal), Lee M. Loomis ‘79 (RG&E), and Richard E. Rice ‘79 (Midtown Holdings). RES Engineers' Joint Dinner Chair, Lee Loomis, reported on the recent dinner; receipts of $4,888, expenses of $4,581.75 left a (modest) profit of $306.25.

Editor’s note: Several letters-to-the-editor (pro and con) continued in this issue, addressing the subject of “editorial & response” to a previous article by Edgar Ferrar of the Genesee Valley People’s Power Coalition, criticizing RG&E and calling for conversion of the investor-owned utility into a municipal utility. The RES Board had decided that, while the RES would modify its editorial policy to further ensure fairness to the magazine’s contributors, the Society’s magazine would continue to print any letters on this particular topic.

The featured article in this issue, written by RES Past-President, Dr. Richard A. Kenyon, described in detail, the design, construction, operation and intended markets for the various outputs of the planned Monroe County Resource Recovery Facility (RRF). This project, emanating from a 1976 study and report by the seventyplus members of the RES’ OPERATION RESOURCE Task Force, was intended to become a revolutionary, but reliable way of dealing with the County’s 2,000 ton/week solid waste stream. This would be done such that maximum value would be derived from separating, classifying, and repurposing the reusable elements of the waste stream. Dr. Kenyon, leader of the RES’ effort, subsequently became chair of the Citizen’s Advisory Committee for the RRF. A Solid Waste Advisory Committee was formed to support the work of the County’s Director of Solid Waste and the County Director of Public Works. This Committee assisted in the preparation of the Request for Proposal (RFP). Later renamed

the Resource Recovery Advisory Committee, it was made an official committee of the County Legislature, responsible to the County Manager. An experienced consultant was retained to research and develop markets for the recycled materials emanating from the RRF. The RRF Advisory Committee then participated in the selection of the contractor (Raytheon Service Company) best qualified to design, construct, and then operate the facility for the first five years. Later on, in the process of identifying markets for the output of the RRF, RG&E emerged as an important partner. Included in the output of the facility would be 1,200 tons/day of refuse-derived fuel (RDF). RG&E became involved as a possible customer for approximately one-half of this, at its coal-fired Russell Station, in Greece. At this juncture, it would be still be two years until the RRF would go into operation. Those involved in this project were very optimistic as to its eventual success in dealing with the untenable problem of the eighteen landfills in the Monroe County area, and the three, now-defunct, City of Rochester trash incinerators that had recently been closed and converted into transfer stations. In a related article by RES Member Gordon J. Keenan, a description of the successful resource recovery/municipal electric generation system in Ames, Iowa, was detailed.

Subsequent articles in this series will describe the RES' continuing outreach to other technical societies as it considered its role in this and the larger community, along with more of the activities of the RES as it moved to be of greater service to its membership, especially those suffering from current economic crises, and adopted a greater role in shaping the future of the City and its environs. Noted also, will be the contributions made by RES members in the struggle to meet the challenges coming out of World War II and the Korean Conflict, as well as a hoped-for period of post-war growth and prosperity. These articles will also feature an impressive array of RES activities in support of post-war re-emergence of Rochester area industry, and the continuing prosperity of the second-half of the 20th Century. We welcome your questions and comments on this series.

RES News - Tutoring Team

Dr. Walter Cooper Academy; Emerging from the Pandemic…

The 2022-23 School Year opened successfully at Dr. Walter Cooper Academy, on Wednesday, September 7th with 333 eager students...

NY State Department of Education – School Receivership

Dr. Walter Cooper Academy is one of six elementary schools in the City School District that have been designated as “Receivership Schools”. This occurs when a school consistently performs at low levels in student test scores (ELA, Math, Science and Social Studies), falls behind in proficiency for ESOL (non-English speaking students), or has too many (>10%) chronically-absent students.

Such schools are required to form Community Engagement Teams (CET’s) and execute a Comprehensive Education Plan to improve outcomes for its students.

In response, our School (#10), has developed such a Team (Lee Loomis serves on this Team) and has implemented a Plan to extricate itself from “receivership”.

Recent reports show that our students’ “scores” are improving and that, our English for speakers of other languages (ESOL) students are making significant progress in their English language proficiency, and that among the six Receivership Schools, our daily attendance has risen to 85.1%, second place among the Receivership Schools, eleventh place overall.

Our school’s Community School Site Coordinator, Michele White, has continued helping us plan for the resumption of the in-person operation of the RES Tutoring Team, in the Fall of 2022. She has reported recently that the teachers are in the process of assessing their students, toward identifying those in need of some “extra attention”. This will result in the assembling of a menu of teacher/student tutoring needs. From this, a weekly tutoring needs schedule will be developed. This will be circulated among our RES Tutors, and inviting our RES Tutors to volunteer for these tutoring assignments.

This is pretty much the process/protocol we were following from 2014-19, before it was interrupted, first by series of drastic 2018-19 RCSD budget cut-backs/layoffs, and then the COVID-19 pandemic, and we are looking forward to its resumption.

We have begun assembling our 2022-23 RES Tutoring Team…

Nimble by Design...

If you are an EV owner, or just observing the nuances across different EV manufacturers, you might observe what I have, some manufacturers produce vehicles that are designed to be more nimble than their competitors. I’m not referring to nimble in the sense that the vehicle is better handling through the curves on mountain roads in Vermont, but that the vehicle platform can be adapted and upgraded.

If you own a vehicle from a legacy manufacturer such as Hyundai, Ford or Volkswagen, does the manufacturer respond to feedback about a feature you’d like to see improved? Would you expect them to implement that change on the vehicle you own, or in the next model year? Probably not likely with the vehicle you own. Many owners find that when there are important functional updates or recalls to their vehicle, it requires scheduling a visit to the dealership and may involve replacement of parts. While these brands do provide some over-the-air updates, it’s often been things like the format of the navigation screens, or changes to the menus. Both Volkswagen and Ford have provided one or two efficiency updates over the air. Even though all three of these manufacturers are utilizing their own new EV platform since 2021, they all have repurposed parts of their electronic dashboard that was previously used in gas vehicles, so you might see a message to “check fuel level” on your EV – even though you a are fully charged. These manufacturers have designed vehicles that are each great and have leading edge next generation products.

By comparison if you own a Tesla, Rivian or other “next generation” car company product, the feedback you provide could result in future changes to how your car functions. Recent examples include Rivian adding the ability for their vehicles to “kneel” when parked to make it easier for both people and dogs to get in and out. Tesla also continues to push out over the air updates to its cars, sometimes weekly. Sometimes they break things and correct it the next release. Tesla recently had a recall that was addressed by a simple over the air update, it did not cost them millions of dollars or owners the inconvenience of scheduling

get IT done

an appointment. In an article published November 8th, 2022, the website Teslarati reported that Tesla’s filing of the mandatory recall included the following statement “As of November 1, 2022, more than 97% of the affected vehicles installed firmware release 2022.36.5 or a later firmware release. No further action is necessary from owners whose vehicles are equipped with firmware release 2022.36.5 or a later firmware release.”

Because both the manufacturers and vehicles are nimble by design, they are better able to respond to their customers’ needs, address safety concerns, and provide us with better products. I prefer purchasing products from organizations that are responsive, nimble, and service oriented. I look for these attributes when recommending and implementing solutions whenever possible.

Focusing on IT systems for a bit, there are many legacy applications that still function well, but they have not yet been adapted or upgraded to meet the latest mainstream privacy or authentication features that are expected in modern organizations. In today’s IT systems, developers of solutions cannot afford to sit back, they need to be both nimble and responsive to the ever-changing environment that is driven by customers, regulators, and communities demanding increased security and privacy.

Over the next few years, I’m hopeful that more organizations will embrace the value of being nimble by design, not only within their products and services, but also how they operate.

Think About IT!

Building and Testing the Webb Telescope for Space Success

by Tony Whitman, Chief Systems Engineer, L3Harris Technologies

the

primary

shape.

The James Webb Space Telescope is hugely successful with unprecedented detail in space images to start decades of astronomical science development and the capability to see back in time to the first light emitted in our universe. Planning for this telescope began at L3Harris Technologies more than two decades ago. A project of this complexity was parsed among many entities, thousands of engineers and scientists, and tens of thousands of technicians to make this telescope a reality. L3Harris accepted the challenge of building the largest precision space telescope and testing the optical and thermal performance of the telescope at temperatures down to 18 Kelvin with the help and expertise of numerous companies and academia in the New York Finger Lakes region.

Optically Precise Integration across Twenty Feet

The optical function of the Webb Telescope consists of the telescope capturing light from the universe

Center of Curvature optical assembly (CoCoa) was built by L3Harris with subcontractor Micro Instruments. CoCoa tests on Webb’s

mirror segments were critical because they informed engineers if all of the mirrors work together to make a telescope that has the correct

and delivering those photons to the instruments with their detectors, mechanisms, electronics, and thermal radiators. The Optical Telescope element and Integrated Science (OTIS) instrument module combination is approximately 26 feet tall and 22 feet in diameter. Across this distance, the optical components were integrated to within tolerances on the order of hundredths of an inch and with precision of thousandths of an inch.

This integration was in the presence of significant structural sag due to gravity. Although the Webb launched in one of the largest rockets available, the large telescope structure needed light weighting and strength optimization to survive launch. The telescope was designed for gravity and thrust along the tangent of the primary mirror. Integration was easier with gravity perpendicular to the primary mirror. The optics needed to be located precisely for zero gravity operation. This meant meticulous tracking of mass elements, expert understanding of the gravitational effect on the structures, careful

communication with the hardware designers from other companies including international partners, and triple checking predictions. Also, the change in the structure sag was tracked every time an optical component was integrated in order to set the target location for the next optical

A partial check of the successful integration occurred during the optical test on the ground, but the true proof of this flawless integration were the perfect first pictures released from operation in space.

Testing Performance in Simulated Space

The Webb telescope's beautiful,

robot arm.

Although unable to switch off gravity, the ground test simulated the temperature and darkness of space with only a handful of light sources. One of the largest vacuum chambers available in the United States was originally built to test the Apollo lunar module in the 1960s, located at the Johnson Space Center. The chamber was transformed from testing a manned mission to testing an ultra-clean and thoroughly dark optical mission. The chamber was fitted with a helium refrigerator and the interior shroud was able to reach 18 K, a temperature below the freezing point of oxygen. A liquid nitrogen shroud surrounded the helium shroud. The chamber used up to seven tankers of liquid nitrogen per day to cool the telescope down to space temperatures.

Given sensitivity of the optical test (able to detect vibrations from a person walking on the floor outside the chamber), the top of the chamber was fitted with vibration isolators to hang the optical test equipment and telescope below. Nine tons of structure and test equipment were safely hung above the multi-billion dollar telescope.

Behind and underneath the telescope were thermal simulators, thermal conduction straps, and thermal radiation sinks designed to steer heat from the instruments’ electronics towards space and away from the telescope to keep the telescope cold. The simulators replaced the tennis court-sized sunshield – too big to fit in the chamber. The infrared telescope is kept cold to prevent self-generating infrared radiation that

First Time Alignment of Segmented Mirror Telescope System inside a Vacuum Chamber

The telescope was unfolded outside the chamber, rolled into the chamber on rails, and then suspended from the vibration isolators. The first trick was understanding where the mirrors were located after a 400F cool down. Laser measurement technology designed for human operation on a production floor aligned the mirrors for integration. That technology and humans do not operate well in vacuum. Rather, photogrammetry was less sensitive to pressure window effects. Photogrammetry uses a large sample of twodimensional pictures from many different angles and mathematical usage of the parallax effect to determine locations of points in three dimensions. A camera was gimbal mounted on the end of each of four windmills on the walls of the chamber near the top to allow the telescope to roll in underneath. Retro-reflector

targets were placed on all the mirror assemblies to reflect the flashes from the cameras. This technology was capable of reaching an accuracy under one hundredth of an inch – within the capture range of new interferometry technology.

Interferometry was used to measure the optical quality from the center of curvature of the nearly parabolic primary mirror. For a smoothly varying monolithic optical surface the phase change can be traced along the surface to keep track across cycles of the laser source wavelength. For Webb, the primary mirror has segment breaks with ambiguity of the number of cycles of wavelength in the jump between segments. This was solved using the beat frequency between a fixed laser and an adjustable wavelength laser to generate an effective wavelength over a millimeter long.

The next challenge was the optical test of the rest of the telescope. Typically, telescopes are tested using a point light source at the image which projects backwards through the telescope to generate a collimated beam from the primary mirror. Then a flat mirror larger than the diameter of the primary mirror reflects the collimated beam back through the telescope to measure the quality of the point image in the detector. This approach could not be employed on Webb.

Instead, optical fibers were cantilevered over the top of the primary mirror in the shadow of a secondary mirror strut to inject light at a focus of the telescope to provide the sources. The formidable challenge was getting a 22-foot diameter mirror to achieve flatness and stability at the cold test temperature within a reasonable time hanging safely over the telescope with the ability to tip and tilt to move the image to the various locations on the detector. Instead, a careful test plan was engineered with the use of three sub-aperture flat mirrors built using glass with an insensitive thermal expansion curve at these test temperatures. Each of these smaller mirrors was placed at the intersection of three primary mirror segments. Then through the use of two optical testing techniques, Shack-Hartmann and phase diversity phase retrieval, the telescope was fully tested optically and exercised through each step of the on-orbit alignment process.

Team Successes

Crews from L3Harris’ Rochester, New York facilities rotated long days and weeks at the Goddard Space Flight Center in Maryland for the meticulous telescope integration and at the Johnson Space Center in Texas for the careful test campaign. For added fun, Mother Nature threw in Hurricane Harvey in the middle of the test. The

Ejections from the star have cleared out cavities above and below it, whose boundaries glow orange and blue in this infrared view. The upper central region displays bubble-like shapes due to stellar “burps,” or sporadic ejections. Webb also detects filaments made of molecular hydrogen that has been shocked by past stellar ejections. The edges of the cavities at upper left and lower right appear straight, while the boundaries at upper right and lower left are curved. The region at lower right appears blue, as there’s less dust between it and Webb than the orange regions above it.

It is a powerful thing to redirect a 525-foot asteroid with a spacecraft moving at 14,000 mph, and Dmitriy Bekker was one of the engineers who made it happen.

Bekker ’07 BS/MS (computer engineering) is part of the DART – Double Asteroid Redirection Test team that impacted the asteroid Dimorphos on Sept. 26. Its mission was to test asteroid deflection technology—a means to defend Earth by changing the motion and speed of an asteroid.

“This was a test of planetary defense technology. We collected data from this impact so that we have a better idea of how to do this in the future if our planet is ever threatened,” said Bekker, an embedded systems engineer at Johns Hopkins University Applied Physics Laboratory (JHUAPL). The lab is one of NASA’s partners in the

development of technology and scientific instruments for space missions.

Last fall, NASA launched the DART spacecraft, built at JHUAPL. DART headed toward the Didymos asteroid system millions of miles from Earth, where it encountered the moonlet Dimorphos. While there was no danger to Earth from this asteroid, it was selected to measure how the small moon’s orbit would change due to the impact of the spacecraft. NASA predicted a 10-minute orbital change; DART shortened the orbit by 32 minutes.

“What was really impressive was that we had Hubble, James Webb, and other telescopes all over the world observing and watching this pre-planned, cosmic fireworks display that we all had a big part in.”

RIT engineering alumnus is part of DART team that changed the speed and path of an asteroid, continued...

Bekker worked on the imager DRACO—the Didymos Reconnaissance and Asteroid Camera for Optical navigation—and led the development of the high-tech camera’s embedded processing system that was used to analyze images and assist with targeting. He also had a role in developing the displays and screens to visualize the data coming back to Mission Control from the spacecraft.

“We had a great team designing, building, and testing the spacecraft,” he said. “Once we launched and were in space, we had to practice operating the spacecraft. It was like learning to drive a car.”

Except that the car was a 1,300-pound spacecraft.

He learned to “drive” through a combination of coursework at RIT and several diverse and challenging co-ops at some of the top research labs in the country—what he termed an engineering wonderland. At Brookhaven National Lab, Bekker worked on data acquisition software for a large laser system. He then moved to a program at NASA Armstrong Research Center, working on instrumentation for research aircraft, and later interned with the NASA Jet

Propulsion Lab, where he would eventually be hired after graduation.

“Many folks in computer engineering go to companies like Microsoft, Intel, or Micron, to name a few,” said Bekker, who is originally from Brighton, N.Y., and who often comes to campus to represent Johns Hopkins APL at the annual Career Fair. “For those that come from a similar background of computer engineering, computer science, and electrical engineering like I experienced here at RIT, there’s a career path out there that needs this background in engineering to contribute to fundamental research.”

And to contribute to work on new space missions.

DART resonated with people because of its easy-tounderstand objective. It was simple in its focus of hitting an asteroid, checking if the technology works, and improving for the future.

“NASA is interested in enabling commercial industry to get us back to the moon. And Johns Hopkins Applied Physics Lab is proposing the instrumentation that might go into these projects,” said Bekker. “I often say that the projects I am working on now, even the DART mission, they all feel like larger and longer senior design projects.” q

2023 ENGINEERING SYMPOSIUM

The 2023 Engineering Symposium has been tentatively scheduled for Tuesday April 25, 2023

Message from the MPES President

I recently attended the NYSSPE Fall Meeting in Saratoga Springs. It was m y first NYSSPE meeting. I found the meeting to be very well organized and I really enjoyed the speakers and the subjects that they presented. It was also a great opportunity to network with other engineers and vendors of some of the products we use in the profession.

The organizational meeting on Saturday was quite interesting. I now have a much better sense of the NYSSPE organizational structure. I would highly recommend that you attend the NYSSPE Annual Conference, June 8-10 at the Hyatt, 125 E. Main St., Rochester, NY, and experience it for yourself.

A topic of discussion that came up at the NYSSPE organizational meeting was the lack of race, gender, and age diversity, not only in NYSSPE, but across the entire engineering field. As I looked around the room at the Saratoga Springs meeting it was quite clear to see, as it was nearly all older white men. We can certainly do better. If you are reading this and you are on the fence about getting involved in a local engineering societ y, just do it! If you are already involved, please encourage other engineers to join you. Often all it takes is for you to ask them . If they need more convincing, just remind them that engineering societies are great opportunities to network with people with similar interests and to learn more about how best to protect the health, safety, and welfare of the public. Who could say “no” to that?

Respectfully, Bill Grove, PE

As always, we encourage active membership in the Monroe Professional Engineers Society. We are constantly striving to improve your membership but we always need more help. If you are interested in becoming an active member or have any questions, please email me at grove.engineering@yahoo.com or contact MPES through our website at www.monroepes.org/contactus/

President's Message

We are very excited to report that the Rochester ASHRAE Chapter has had a great start to 2022. The Chapter is very encouraged by the meeting attendance so far. For the 2021-22 year we were struggling to hit 40 members in attendance. For the November meeting our attendance was 90! This is really great news for us since it was a risk for the chapter to use the Strathallan for meetings if attendance did not increase. Great job by Jim Parks for setting up a great program and his work to choose our new venue. Thank you to our membership for showing up to support our Distinguished Lecturer Paul Torcellini for his presentation on “How Do We Get To a Decarbonized World.”

For the first time in more than a decade we are very pleased to announce that for 2022 we have selected recipients for the Charles Lynch Memorial Scholarship and the Jack Betlem Memorial Scholarship. This is truly a highlight for the Chapter this year. Two students at MCC have received a scholarship to help them on their way to the field of HVAC. Credit to Mike Benedict for his hard work to keep pushing this past the finish line. We will be welcoming
