Additional Benefits Isolated Power Systems Increase the Life of Medical Devices

M

any of us who provide electrical products to the healthcare industry are aware of the benefits associated with Isolated Power Systems (IPS) in hospital operating rooms, critical care, and intensive care areas, for their ability to provide continuous power in the event of one line to ground fault while eliminating the danger of electrical shock. These systems were first introduced into the hospital environment over fifty years ago as a way to reduce the risk of explosions in operating rooms and other areas where flammable anesthesia agents were used. Today, these types of flammable gases are no longer in use and some feel the added cost of IPS is thereMedical care providers are becoming fore not justified, resulting in ongoing de- increasingly dependent on electrically bates involving their safety benefits versus powered apparatus for the preservation of their cost. life of hospitalized patients.

more cardiac operations are performed every year, in many of which the patient’s life depends on artificial circulation of the blood; in those and other operations, life is often sustained by means of electric impulses applied directly to the heart muscle to stimulate and regulate its action.

Many large hospitals have over 10,000 pieces of equipment, many of which cost tens of thousands of dollars each and often more. Should one of these instruments fail or be damaged for any reason, including poor power quality, not only would the resulting repairs be costly, but more importantly, such a failure could jeopardize the life of the patient.

This increased use of sensitive electronic systems in the hospital environment has created a growing need for a “clean” supply of power, free of noise and transients. Data storage and monitoring equipment is often extremely sensitive to line transients and noise frequently present on power lines. The IPS contains a high quality shielded isolation transformer which provides a convenient and effective means of greatly reducing or even eliminating line-to-line and line-toground noise on power feeders. Many manufacturers of noise-sensitive equipment have recognized the problem created by transients and noise on their equipment’s input line and have provided a measure of protection as an integral part of their equipment. This protection, however, may not be adequate for frequent or serious disturbances. Although the primary reason for IPS design and installation was not to achieve this noise reduction, but to provide a low leakage secondary power system for safety reasons, we must recognize Continued on page 8

this other “built-in” but less obvious advantage of IPS when comparing it against conventional grounded systems.

There are two types of noise that affect medical devices typically found in hospital critical care areas: common mode noise, the most prevalent type, and transverse mode noise. Common mode noise refers to electrical interference existing in common on all current-carrying conductors and measurable as a ground referenced signal. In typical hospital environments, large quantities of this type of noise can be generated by high-power equipment using phase-control techniques, including variable speed motor drives, elevator soft-start controls, and lighting dimmers, as well as other types.

In these applications, power savings or other desired effects are accomplished by using only a portion of each cycle of the AC waveform. At the instant during the waveform cycle when the device switches “on”, a large transient current flow can be created in the “neutral” conductor, which can impress a high transient voltage on all conductors of the power line feeder proportional to the impedance of the neutral conductor’s path to ground.

The IPS acts as a filter to safeguard medical electronics by blocking common mode noise and harmonics from reaching equipment connected through it. An IPS consists of the following key components: an isolation transformer, a line isolation monitor, and a circuit breaker panel with ground bus. The isolation transformer is the component responsible for blocking noise while providing surge suppression.

This transformer has separate primary and secondary windings and generally a shield between them. Its main purpose is to allow re-referencing of output connections and to reduce conducted electrical noise.

An isolation transformer transfers to its secondary only those voltages that differ between legs of its primary, and therefore blocks common-mode noise and transients from its input circuit to its output windings. This attenuation, or reduction in amplitude, could be as high as one million to one.1 A study conducted by IBM estimates a power surge of 100 to 1,000 volts occurs at least once per day in every electrical environment, possibly leading to system lock-ups, lost productivity and 8

even catastrophic equipment damage or data loss. Surges can also degrade lighting, HVAC and elevator controls as well as chiller systems - each potentially leading to life-threatening problems quite apart from dedicated medical devices.

Surge related issues result in nearly $80 billion in losses for the U.S. economy, according to the Worldwatch Institute.

These equipment-damaging electrical pulses are also a factor in patient care and the filling of landfills with harmful electronic waste due to equipment failure.

In an article written August 5th, 2009 on Dotmed.com, William Goldbach, a senior life member of the Institute of Electrical and Electronics Engineers (IEEE), wrote, “Microprocessors read in-

has been a leader in this field for over 50 years and continues to develop new technologies and advantages to increase the value and lower the total cost of ownership for these systems. The onetime cost of installing isolated power typically represents 6-8% of the total electrical distribution equipment installed in a newly constructed hospital. The long term savings associated with these systems far outweigh the costs of implementing them into your hospital system. PG LifeLink works with engineers, contractors and specifiers to assist in making a project as economical as possible.

Conclusion Many areas of modern healthcare facilities represent the confluence of electrically powered devices. Although the main reason for isolated power in hospital critical care areas is to reduce the potential of electrical shock, isolated power systems provide additional benefits beyond an added safety layer for the patient and staff. As identified in this article, hospitals are able to increase the reliability and possibly even extend the life of expensive medical equipment. Although there are other costly methods available to reduce common mode noise, isolated power inherently includes this beneficial attribute, adding value by being included as part of electrical distribution systems.

Because IPS provide a solution to common mode noise found in electrical distribution systems throughout hospitals and also provide additional safety, it is our judgment, based on the facts presented in this paper, that the benefits of IPS easily outweigh the incremental costs. Isolated Power Systems provide both a safer overall system than grounded power and a less hostile electrical environment for critical electronic life-support equipment, and should be considered standard equipment for critical care areas. ❏

formation through current pulses as binary code (zeros and ones). As equipment is turned on and off, voltage and current pulses, known as transients, are generated.

Three-Phase, 3-Wire Systems

In this type of system, commonly known as the “DELTA” configuration, the voltage between each pair of line wires is the actual transformer voltage. This system is frequently used for power loads in commercial and industrial buildings. In such cases, service to the premises is made at 208V, three-phase. Feeders carry the power to panel boards supplying branch circuits for motor loads. Lighting loads are usually handled by a separate single-phase service. The 480V distribution is often used in industrial buildings with substantial motor loads.

ower economics now play a critical role in industry as never before. With the high cost of power generation, transmission, and distribution, it is of paramount concern to effectively monitor and control the use of energy.

The electric utility’s primary goal is to meet the power demand of its customers at all times and under all conditions. But as the electrical demand grows in size and complexity, modifications and additions to existing electric power networks have become increasingly expensive. The measuring and monitoring of electric power have become even more critical because of down time associated with equipment breakdown and material failures.

For economic reasons, electric power is generated by utility companies at relatively high voltages (4160, 6900, 13,800 volts are typical). These high voltages are then reduced at the consumption site by step-down transformers to lower values which may be safely and more easily used in commercial, industrial and residential applications.

Personnel and property safety are the most important factors in the operation of electrical system operation. Reliability is the first consideration in providing safety.

Balanced vs. Unbalanced Loads

A balanced load is an AC power system using more than two wires, where the current flow is equal in each of the current carrying conductors. Many systems today represent an unbalanced condition due to uneven loading on a particular phase. This often occurs when electrical expansion is affected with little regard to even distribution of loads between phases or several nonlinear loads on the same system.

Demand The amount of electrical energy consumed over time is known as demand.

Demand is the average load placed on the utility to provide power (kilowatts) to a customer over a utility-specified time interval (typically 15 or 30 minutes). If demand requirements are irregular, the utility must have more capability available than would be required if the customer load requirements remained

Page 14

Continued from page 12

constant. To provide for this time-varying demand, the utility must invest in the proper size equipment to provide for these power peaks. Brief high peaks such as those present when large equipment initially comes on line are not critical in the overall equation because the duration is short with respect to the demand averaging interval.

Consumption

Power factor is the ratio of ACTUAL POWER used in a circuit to the APPARENT POWER delivered by a utility. Actual power is expressed in watts (W) or kilowatts (kW); apparent power in voltamperes (VA) or kilovoltamperes (kVA). Apparent power is calculated simply by multiplying the current by the voltage.

Power Factor =Actual Power = kW Apparent Power kVA

Watts and vars are instantaneous measurements representing what is happening in a circuit at any given moment. Since these parameters vary so greatly within any period, it is necessary to integrate (sum) electrical usage over time.

The fundamental unit for measuring usage is the watt hour (Wh), or more typically the kilowatt hour (kWh). This value represents usage of 1000W for one hour. Typical costs in the United States for one kilowatt hour range from 8 to 15 cents.

Certain loads (e.g., inductive type motors) create a phase shift or delay between the current and voltage waveforms. An inductive type load causes the current to lag the voltage by some angle, known as the phase angle.

On purely resistive loads, there is no phase difference between the two waveforms; therefore the power factor on such a load will be 0 degrees, or unity.

electric motor represents a partially inductive load consisting of actual current which will be converted into actual power, and magnetizing current which generates the magnetic field required to operate the electric motor. This magnetizing current, called the reactive current, corresponds to an exchange of energy between the generator and the motor, but it is not converted into actual power.

Reactive Compensation Power Reactive compensation power refers to the capacitive values required to correct low power factor to as close to unity (1.0) as possible. Most industrial loads are inductive, so the load current lags the line voltage by some degree. In order to bring the value closer to unity, something must be added to the load to draw a leading current. This is done by connecting a capacitor in parallel with the load. Since a capacitor will not dissipate any real power, the charge for real power will be the same.

FEATURE • AEMC® Instruments AEMC recommends consulting a power factor correction capacitor manufacturer prior to any installation to reduce the possible effects of harmonics, resonance, etc.

Electrical Harmonics Until fairly recently, power quality referred to the ability of the electric utilities to supply electric power without interruption. Today, the phrase encompasses any deviation from a perfect sinusoidal waveform. Power quality now relates to shortterm transients as well as continuous state distortions. Power system harmonics are a continuous state problem with dangerous results. harmonics can be present in current, voltage, or both. It is estimated that as many as 60% of all electrical devices operate with non-linear current draw.

Utility companies invest millions of dollars each year to ensure that voltage supplied to their customers is as close as possible to a sinusoidal waveform. If the power user connects loads to the system which are resistive, such as incandescent light bulb, the resulting current waveform will also be sinusoidal. However, if the loads are nonlinear, which is typically the case, the current is drawn in short pulses and the current waveform will be distorted. Total current that is then drawn by the nonlinear load would be the fundamental as well as all the harmonics.

Continued from page 16

from inadvertent tripping of circuit breakers to dangerous overheating of transformers and neutral conductors, as well as heating in motors and capacitor failure.

Harmonics can cause problems that are easy to recognize but tough to diagnose.

It is becoming increasingly important to understand the fundamentals of harmonics, and to be able to recognize and monitor the presence of damaging harmonics. Harmonics within an electrical system vary greatly within different parts of the same distribution system and are not limited simply to the supply of the harmonic producing device. Harmonics can interact within the system through direct system connections or even through capacitive or inductive coupling.

A harmonic may be defined as an integer multiple of a fundamental frequency. Harmonics are designated by the harmonic number. For our discussion, we will focus on the 60Hz power frequency. The second harmonic would be two times the fundamental or 120Hz. The third would be three times the fundamental or 180Hz, and so on.

Nonlinear equipment generates harmonic frequencies. The nonlinear nature of a device draws current waveforms that do not follow the voltage waveform. Electronic equipment is a good example. While this broad category encompasses many different types of equipment, most of these devices have one characteristic in common.

They rely on an internal DC power source for their operation.

Loads which produce harmonic currents include: • Electronic lighting ballasts • Adjustable speed drives • Electric arc furnaces • Personal computers • Electric welding equipment • Solid state rectifiers • Industrial process controls • UPS systems • Saturated transformers • Solid state elevator controls • Medical equipment This is by no means an exhaustive list of equipment which generates harmonics. Any electronic-based equipment should be suspected of producing harmonics. ❏

The CAT5/6 cable can certainly handle it but it does give you reason to pause and pay extra attention to what you are doing. To help keep PoE safe, the IEEE has published standards with numerous provisions: One assures that the device providing the PoE will not provide the power until it sees an appropriate PoE load. But many of the PoE supplying devices in the market today seemingly fail to follow that standard directly. Some devices always have the 48V switched ON.

Every device needs power and up to a couple of years ago, the power line always led to an AC outlet. That is changing fast as more and more computer and network devices take advantage of the new power scheme called Power over Ethernet (PoE)… putting the power on the same CAT5/6 cable as the data.

The Advantages of PoE The advantages of PoE over traditional power sources are growing… and it won’t be long before a knowledge of PoE becomes part of the installation job.

To be useful during installation time, a tester should be capable of detecting the presence of both an active data device and a power source for the device. One such tester is our own Network Power Panel.

The Network Power Panel continually scans the CAT5/6 cable’s 8 pins testing

for active network devices and voltages (PoE included). Once spotted, one of the Power Panel’s 3 ultrabright LEDs alert you to the presence of either an active device or voltage. The Network Power Panel categorizes the device as either “Network”, “Phone” or “Power” (POE). If, by chance, all types of devices exist, then all the LEDs will light.

These ultrabright LEDs are the only indication that most users need that a data path and PoE is available for their device. But there is plenty more to learn from the Network Power Panel if you wish. For instance, the “Network” LED’s screen displays the speed capabilities of the device (10, 100, 100, HD, FD) and the cable pair(s) where the transmit pulses exist. The “Phone” device’s screen displays cable pair location and the voltage amplitude of up to 4 phones. And, the “Power” device’s screen displays PoE cable pair location; whether its “midspan” or “endspan” PoE; and the PoE voltage amplitude.

And, if you are using the “inline” model of the Network Power Panel, insert it in between the device providing the power (eg PoE switch) and the device (eg VoIP phone) and measure the power consumption (watts) of the device. The power measurement capability is one of the most popular features of the Network Power Panel.

The Right Tool Saves Time Like any installation, the install of VoIP phones, IP cameras, access points and other PoE devices involve more troubleshooting than desired. The Network Power Panel is the perfect detective tool because it is designed to detect PoE; display its location on the cable; and display the amplitude of the signal. It additionally detects network devices (indicating 10, 100, 1000, HD, FD) and phones. Picture# 1 shows 48VDC of PoE on pairs 1/2 and 3/6 (“PoE endspan”). Picture# 2 shows the power draw of a recently installed VoIP phone (4 watts).

The Network Power Panel is available two ways: As a standalone unit (model POE1000) for $129.00 or bundled in the Cable&Power Kit (CPK1000) which includes the popular Real World Certifier for $599.00.

Simplifying Load Bank Testing of Standby Generators for Critical Operations Power Systems (COPS)

When designated as a COPS the power operations systems within such facilities typically rely on emergency power generation systems for back-up in case of power loss from the grid. It’s important that contractors understand that DCOAs are mandated by NEC Article 708 and NFPA 110 to regularly test their emergency power systems in order to ensure their reliability. This is accomplished by “Load Bank Testing” which allows the contractor or MRO electrician to confirm that the installed emergency generator works properly when required to provide back-up power.

Load bank hook-ups can be challenging, and they make COPS susceptible to power loss during the testing, since the permanent generator has been disconnected from the system. For this reason most test procedures require the connection of a temporary back-up generator to the system while the permanent generator is being tested.

In order to streamline and simplify the regular load bank testing Continued on page 26

PRODUCT SPOTLIGHT • ESL Power Systems, Inc.

of DCOA back-up power systems, ESL has introduced TripleSwitch™, a newly developed electrical disconnect product designed to dramatically simplify the method used to test emergency backup generators for Critical Operations Systems (COPS), while reducing the required labor.

“Load bank testing of any permanently installed dedicated generator is an absolute maintenance must,” said Carsten.

“Load bank testing assures that the generator will function properly if the grid power is lost. The TripleSwitch is best located where it makes it convenient to connect both the load bank tester and an emergency temporary back-up generator. Installation requires routing the output cables from the permanent generator to the TripleSwitch; then running cables from the TripleSwitch to the automatic transfer switch.”

Before the TripleSwitch was developed, one customer – a large water and wastewater treatment district located in California — told ESL that the maintenance manager planned to purchase two large 400Amp knife edge switches to support their load bank testing. This solution presented drawbacks such as the lack of overcurrent protection and/or risk of fuse replacement during critical times. Additionally, the maintenance team knew that interlocking would be a cumbersome task.

26

Instead, Tom Zinchuk, Manager of Engineering for ESL, worked closely with the water/ wastewater utility’s staff to develop a simpler and safer cam-style electrical solution that met the water utility’s needs to test their twenty-eight generator locations while reducing the demands on the staff to complete the labor-intensive testing. “The TripleSwitch product line was developed to provide a centralized and convenient means to disconnect a permanent generator from an ATS, while at the same time allowing the permanent generator to be connected to a load bank, and a second emergency generator to be temporarily connected to the ATS,” explained Zinchuk.

“This is a typical preventive maintenance application for any location that employs a permanent generator with an ATS. However, the TripleSwitch would work in any application where there is a need to safely disconnect certain power generation units from each other, while easily connecting other alternative power sources,” Zinchuk added.

Michael Hellmers, President of ESL, explained that the TripleSwitch affords operators a simple and efficient solution.

“Our unique TripleSwitch design has a much lower cost, a smaller footprint, and virtually eliminates wiring mistakes under emergency situations,” said Hellmers.

By installing a TripleSwitch system,

contractors enjoy a number of important benefits when testing systems up to 800 Amps, including a faster way to disconnect and test a permanent generator, simplifying the connection using the installed TripleSwitch rather than disconnecting and reconnecting the generator’s conductors.

With TripleSwitch, customers enjoy faster testing of their COPS generator installations which reduces maintenance labor costs every year, plus the facility can then easily switch out a temporary power generator while a permanent generator is repaired or replaced.

The TripleSwitch line, which is available with current ratings from 70 Amps to 800 Amps, and voltage ratings up to and including 600VAC, promotes increased safety, security and flexibility, while delivering a very cost-effective and easy to use solution for all COPS facilities. ❏ ESL Power Systems, Inc. (www.eslpwr.com) is a global leader in the design and manufacture of modular safety-interlocked electrical power connections, including ESL’s StormSwitch™ Manual Transfer Switch (www.stormswitch.com) with integrated cams. ESL also develops customized power distribution systems for many diverse industrial applications where safety, dependability, and durability are required.

IDEAL Introduces Versatile, Affordable New Step Drill Bits Tool versatility means added value for today’s contractors. That’s why IDEAL has introduced a new line of double-fluted step drill bits that feature a 1/4” hex shank compatible with virtually every drill on the job site, including 3-jaw chuck, impact drivers, and quick change drill chucks.

“Our Quick Change bits are designed to appeal to contractors interested in buying and carrying fewer cutting supplies,” explained Aaron Mattison, Product Manager for IDEAL. “Using only a single bit, contractors can precisely cut multiple-size holes through brass, plastic, carbon steel, cast iron, stainless steel, and hard or soft woods.”

Key to the Quick Change bit’s success is an aggressive split point tip that is twice as fast at initial penetration as conventional step drills. By dramatically reducing penetration time the bit prevents skidding across the surface, while also eliminating the trouble of making a pilot hole or punch.

Each 1/16” multi-diameter step is radius-blended to smoothly transition from one to the next. Hole-size diameters are laser-etched in the flute area for quick and positive identification. The double-fluted design, with its secondary cutting edge, yields more balanced, vibration-free cutting for exact, repetitive holes.

To further enhance cutting performance, the bitsincorporate the most durable, double-tempered high-speed steel available for cutting tools. Three bit sizes are available: 1/8” to 1/2” (#35-521), 1/4” to 7/8” (#35-522), and 1/4” to 1-1/8” (#35-523), along with kit (#35-524) that contains all three sizes in a rugged blow-molded case.

NEMA Publishes LSD 54-2010 The Strengths and Potentials of Metal Halide Lighting Systems The National Electrical Manufacturers Association (NEMA) has published LSD 542010 The Strengths and Potentials of Metal Halide Lighting Systems.

This new white paper, developed by the NEMA Lamp Section, reviews the beneficial characteristics of metal halide high-intensity discharge (HID) lighting, including high energy efficiency and viability in outdoor and other lighting applications. The paper argues for the inclusion of HID lamps in ENERGY STAR® requirements and for allocations of federal funding to help propel further research and development. As described in LSD 54, other benefits of metal halide lighting include long lifetime, high maintained light levels, and the broadest ambient operating temperature range of any light source. In light of the attention given to solid state lighting, the section produced this paper to remind stake-

holders that HID lighting remains an excellent choice for many lighting solutions.

“Continued breakthroughs in technology make metal halide a fantastic option for specifiers and consumers,” said Pamela Horner of Osram Sylvania, chair of the Lamp Section. “These lamps are now one of the most energy-efficient white light sources available on the market, and LSD 54 makes the case for increased use of and investment in this technology.”

LSD 54 may be downloaded at no charge by visiting www.nema.org/stds/lsd54.cfm.
