Editorial An Electrically Safe Nation Electricity is undoubtedly important to a nation’s everyday life; however, it can pose hazards to people and properties. Accidents which are electrical-related often lead to loss of lives and properties. Thus, an electrical safety campaign plays a vital role in keeping the public’s awareness on these kinds of hazards. As Marcus Tullius Cicero would put it, “The safety of the people shall be the highest law.” The Electrical Safety campaign of IIEE has been carried on for three years after the declaration of Proclamation 193 last 2011, stating the month of May as the Electrical Safety Month. For this year, different activities are scheduled for the monthlong event. These include motorcades, unity walk, distribution of flyers, Barangay information drive, and public school inspection to the whole country with the help of different chapters. The campaign includes everybody without exemption, constantly reminding people to practice electrical safety measures as their way of life. IIEE continues to increase public awareness in the importance of electrical safety, constantly reminding everybody that, “Electrical Safety starts with me.”

arm greetings from the office of the National President! I would like to commend the Board of Governors, Committee Officers and Members and the general membership for their dedication and unselfish service to the Institute for the second quarter of 2013. Let us commit ourselves for the betterment of IIEE and for the recognition of electrical practitioners all throughout the globe in accordance with the IIEE’s 2013 theme. IIEE GOVERNANCE I attended the Philippine Technological Council Board Meeting last March 14 which was hosted by Philippine Institute of Industrial Engineers. During the meeting, Mr. Fred Monsada cited that for 194 engineering programs, there’s a need for at least 116 program evaluators per APO. To achieve this, program of activities during the regional conferences must include training of program evaluators. On March 25, I, together with the VP for Internal Affairs, Engr. Alex C. Cabugao, went to Thailand as response to the invitation of International Copper Association (ICA) for the European Union – ASEAN Energy Efficiency Standards Harmonization Initiative for promotion and deployment of Energy Efficient Air Conditioners in ASEAN. We also attended the meeting held on March 26-27.
On April 29, I had a meeting with Holcim Philippines consultant and personnel at the Holcim’s office located at Two World Square Building, McKinley Hills, Taguig City. The discussion centered on the off-site training to be provided by IIEE to the electrical practitioners of Holcim’s different cement plants nationwide. REGULAR EXECUTIVE COMMITTEE MEETING AND REGULAR BOARD MEETING On April 26-27, the 15th Northern Luzon Regional Conference was held at Baguio Country Club, Baguio City. Furthermore, the 4th Regular Board Meeting was held at the same venue on April 27. On May 4, the 5th Executive Committee was held at the IIEE National Office while on May 10, I attended the selection of Outstanding Professional of the Year Award within the electrical engineering’s industry held at the Professional Regulation Commission office. Engr. Arthur N. Escalante, 2009 National President, was adjudged as the winner of the coveted award. Last May 25-26, I have attended the National Mid-Year Convention and 5th Regular Board Meeting which was held at Taal Vista Hotel, Tagaytay City.
On April 6, I visited the newly formed Singapore Chapter which has been under probation since January of 2012. The visit was for the validation of Chapter activities for its promotion to regular status. The Chapter will be under Charter 86 once the required pending documents have been submitted. On April 10, I attended another meeting with ICA held at the IIEE National Office; the primary aim is to discuss another partnership/grant from EU in which IIEE will be EU’s main partner. It is about a Switch Asia Project on the promotion and deployment of high efficiency motors. As of May, IIEE have complied with all the documentary requirements needed by EU for the evaluation of IIEE’s application. The Kick-Off ceremony for the celebration of Electrical Safety Month was held at the IIEE National Office last May 4. There were activities conducted such as: street dancing in the tune of ESEA jingle, unveiling of Electrical Safety Month signage, unity walk, official launching of Cirkito mascot, and info drive around Brgy.

ELECTRICAL SAFETY a way of life Cover Story
T
he importance of electricity varies from one person to another. Nevertheless, electricity is undoubtedly essential to everyone, making everyday lives easier in this advanced world. It is said to be an important element towards economic development. However, without the proper guidelines on electrical safety, lives and properties are at stake to a hazardous environment.
Electrical Inspection in the Philippines
As defined in the 2004 Edition of NFPA 70E: Standard for Electrical Safety in the Workplace, Electrical Safety is “recognizing hazards associated with the use of electrical energy and taking precautions so that hazards do not cause injury or death”.
The Institute describes these accidents as “electrical in origin”. These incidents happen because people often disregard the purpose of electrical safety activities.
In the health safety manual of the Infrastructure Health and Safety Association (IHSA), electrical hazard is described as “a dangerous condition where a worker could make electrical contact with energized equipment or a conductor, and from which the person may sustain an injury from shock”. Appliances in the modern era post varied dangers at home if electrical safety measures are ignored. Electricity can destroy homes and can cause injuries or harm to people. Most tragically, electrical accidents can cause death. According to the Injury and Fatality Statistics by the Electrical Safety Foundation International, there are more than 30,000 non-fatal shock accidents, which occur annually in the United States, while in the Philippines, about 5 workers are electrocuted every week according to statistics. In Dennis K. Neitzel’s The Hazards of Electricity – Do you know what they are?, it is stated that, “Electricity has long been recognized as a serious workplace hazard, exposing employees to electrical shock; which can result in electrocution, serious burns, or falls that result in additional injuries or even death; as well as electrical arc-flash and electrical arc-blast.” The four types of electrical injuries are; direct causes such as, 1) electrocution or death due to electrical shock, 2) electrical shock, 3) burns; and an indirect cause, 4) falls.
16
While reports present fire incidents from electrical causes in the Philippines in 2011 as due to faulty wiring, the Institute of Integrated Electrical Engineers of the Philippines, Inc. (IIEE) explains that, “An electrical system won’t work nor function if, in the very first place, it is faulty”.
Under the Occupational Safety and Health Standards of the Department of Labor and Employment (DOLE) Manila, “No service or power supply shall be connected to any electrical installation by any utility company supplying electricity or by any person until the necessary final inspection is conducted and a safety certificate/permit issued by the Regional Labor Office or authorized representative having jurisdiction over the case”. With regards to this, the Philippine Electrical Code (PEC) is adopted for the standards of electrical safety. The PEC contains guidelines for the assessment and inspection prior to the issuance of electrical wiring permit, with a purpose of “practical safeguarding of persons and property from hazards arising from the use of electricity”. To quote Ramon M. Cristobal, President of the Association of City/Municipal Electrical Engineers and Electricians (ACMEEE), from the 2009 PEC Part 1 Volume 1, “The Philippine Electrical Code is used nationally as the basis for safeguarding persons, buildings and its contents from hazards that may arise from the use of electricity.”
The Month of May is the Electrical Safety Month “Electrical Safety Starts with Me.” This is the slogan of the electrical safety campaign of the IIEE in observance of Presidential Proclamation 193, stating the month of May as the Electrical Safety Month. It was noted in the proclamation that “the main reason for the
THE ELECTRICAL ENGINEEr 2nd QUARTER 2013
occurrence of fires and electrocution from electrical causes is not faulty wiring but ignorance in the use of electrical appliances and gadgets such as overloading of electrical outlets and the use of counterfeit electrical products such as circuit breakers, power strips, extension cords, batteries and holiday lights that can cause fires, explosions, shocks, and electrocutions” Signages of the Electrical Safety Month were displayed in various establishments not only in Metro Manila, but also in the different regions of the country, with the help of the IIEE regions and chapters. In celebration of the Electrical Safety Month, IIEE had its kickoff event at its National office last May 4. The officers of IIEE, headed by its National President Engr. Gregorio R. Cayetano, had a unity walk and motorcade around the barangays of Cubao, Quezon City to promote the campaign. A streamer with this year’s theme, “Working together towards an Electrical Safety Conscious Nation” was also unfurled in front of the IIEE building after the motorcade and unity walk.
around the vicinity of Barangay Immaculate Concepcion, which aims to educate the public with safety procedures with regards to the use of electricity, may it be at home or at the office. Public school inspection was also part of the activities in line with the Electrical Safety Month. Marikina Elementary School and Sauyo High School were inspected last May 18 and May 25 respectively, before the opening of classes. Data gathered from the inspection will be sent to school heads with regards to its electrical connections and installations. Barangay Electrical Safety Information Drive was also conducted in two barangays, Barangay 900 in Punta, Sta. Ana, Manila last May 15, and in Barangay Quirino 2-A in Quezon City last May 31. The activity aims to provide information on electrical safety practices. The Electrical Safety campaign aims to educate the public, from local government officials and private offices to schools and households. To be able to reduce electrical-related accidents and deaths is the principal purpose of the advocacy. Electrical safety should be addressed as a way of life. Electrical Safety advocates, not only here in the Philippines but all over the world, continue to disseminate practicable measures for an electrically safe future.

The program was attended by IIEE officers, staff, CSC aspirants, and Bureau of Fire Protection (BFP) Officer-in-Charge Carlito S. Romero. General Carlito S. Romero stated in his speech, “There is a total of around 3,148 fire incidents traceable to electrical ignition. Roughly, 36% of the total 8,798 fire incidents last year. This year, from January to March, there were 773 fire incidents related to electrical ignition… IIEE is assisting the Bureau of Fire [Protection] to prevent fire incidents traceable to electrical ignition,” General Romero also gave a short lecture for the students who are also present at the event. He is a Professional Electrical Engineer and former co-chairman of the IIEE Electrical Safety Committee.

Static and Dynamic Motor Testing as Part of Predictive Maintenance Programs by Timothy M. Thomas, Baker Instrument – SKF Group Company Abstract Predictive Maintenance Programs, (PMPs), are becoming universally accepted as the best method for maintaining motor reliability within most modern plants and facilities. A complete PMP will include as many technologies as possible with each technology providing vital pieces to the diagnostic puzzle. Periodic static testing and more aggressive dynamic testing of motors are essential parts of predicting the potential for a motor to continue a safe and successful operation. Tracking and trending the results of electric motor testing, on a regular schedule is the most effective method of making intelligent predictions.
Introduction: The Need for Motor Testing The steady, safe and efficient operation of electric motors is essential to the productivity of all plants and facilities. Some facilities including hospitals, airports, major office buildings, and innumerable others have many critical and/or expensive motors. A motor failure could be catastrophic causing lost production and costly emergency repairs. For example, a motor failure at a nuclear plant can cost up to one million dollars a day for critical motors and may have a disastrous, long-lasting impact. Even failures at a waste water treatment facility can have a huge, negative environmental effect and can be very costly. Motors fail due to numerous operational circumstances including power condition, mechanical influences and environmental hazards. According to recent IEEE1 and EPRI2 studies, at least thirty-five to forty-five percent of motor failures are electrically related. Monitoring the motors “electrical health” is, unquestionably, an important and vital consideration. Trending the historical operating condition of a motor makes early detection of any decline in the motors “health” possible. Planning “down time” and having only minor reconditioning repairs instead of a major rewind or replacement is far less expensive in both repair costs and lost production. Since electric motors begin deteriorating the instant they are started, it is necessary to monitor their operating condition on a routine, periodic schedule. Periodic monitoring and trending of data collected and properly diagnosed provides the technician with evidence needed to prepare for down time before a catastrophe occurs. It is no longer practical to just “megger” a motor in order to determine its condition. Plants and facilities depend on a complete Predictive Maintenance Program (PMP) to monitor their operations and plan their repair schedules. A good predictive maintenance program requires both static (and off-
line) and dynamic (or on¬line) testing, with educated and trained technicians monitoring data routinely, with quality equipment. Besides voltages and currents, on-line test equipment must be able to capture and trend torque ripple and torque signatures as well as rotor bar side bands. Off-line testing with modern, high voltage test equipment is essential to getting reliable data. The voltages required to properly test motor windings cannot be reached with impedance based or low voltage test equipment.
On-Line Testing Effective dynamic test equipment must be able to collect and trend all essential data that affects the operation of electric motors. Power condition including voltage level, voltage imbalance and harmonic distortions, current levels and current imbalances, load levels, torque signatures, rotor bar signatures, service factors and efficiencies should be tracked and trended. On-line testing is performed at the motors MCC, at the load side of a variable frequency drive or at an installed port, which allows for on-line testing without opening the MCC. Data is collected through a set of current transformers and corresponding voltage probes. The data collected, processed and analyzed provides the technician with an overall view of the normal operational environment to which the motor is subjected on a daily basis and of how the motor is responding within this environment. Often a motor is subjected to incoming power problems including low or high voltages, voltage imbalances and harmonic distortions. Lower voltages cause higher currents and therefore more heat. Higher voltages cause lower power factors and ultimately higher losses. A small amount of voltage imbalance creates an exponential amount of current imbalance which causes temperature increases. Harmonic distortion also causes thermal stress in motors. Any of these voltage problems can cause severe overheating in the motor even without factually reaching an over-load situation, and excessive heat is the insulation’s major enemy. Some motors are subjected to physical obstacles that cause undue stress. Over greasing, misalignment and over-tightened belts all cause thermal stress. Many motor failures can be traced to load related situations. Erratic torque signatures can be an indicator of load related problems. Broken or cracked rotor bars can also cause premature motor failures. On-line testing identifies these problems and routine trending will reveal the rate of decline. Of major importance to the overall health of a motor also is the “effective service factor. ”Two elements affect the service factor number: real operating power condition (voltage quality) and steady state load conditions. The effective service factor number represents the thermal stress caused by these two conditions on the motor. On-line testing can find and trend all

Technical Feature these motor conditions. Dynamic testing schedules should be tailored individually according to operating time, criticality, and any other important element of operation. Generally, an on-line test should be performed at least quarterly. Motors that begin to show obvious decline or thermal over-stressing should be monitored more closely until the motor can be statically tested or removed from operation and repaired. New and recently repaired motors should be tested as soon as they are returned to service in order to provide a historical record (or baseline) of their performance when the motor is at its “best.”
Off-Line Testing In general, motors are quite reliable and when properly maintained, one should expect at least one hundred thousand hours of continual operation. That is to say, a new motor operated within nameplate parameters should give us at least eleven years of steady use. Unfortunately, motors are almost always subjected to a variety of damaging elements with the end result being a rise in operating temperature. Thermal aging of the insulation is the major cause of insulation failure. Years of testing and numerous studies have shown that, as a “rule of thumb,”“for every 10 degrees centigrade increase in temperature, the winding life is decreased in half.”3 Besides thermal problems, other causes of insulation failures include incoming line related problems. Spikes caused by lightning and surges created by switching and contactor closing contribute to insulation breakdown. Motors are also subjected to mechanical influences including bearing failure, environmental hazards and magnet wire damage caused during the manufacturing process. Even the physical movements of the windings during startups causes wear to the insulation system especially the magnetwire insulation as D.E. Crawford has shown.4 Proper testing of all components of a motor requires a series of tests designed to emulate the conditions the motor will see in the field. It has been proven in numerous studies that low voltage testing, including capacitance, inductance, impedance, et cetera, are not effective tools in verifying insulation problems. Quality off-line test equipment will be able to perform winding resistance tests, insulation resistance tests, high potential (HiPot) tests, polarization index, and surge tests at IEEE, NEMA and EASA accepted standards. Top quality test equipment will automatically run a series of pre-programmed tests and provide a complete final report. This automatic equipment will stop testing before any damage is done to the windings. The resistance test verifies the existence of dead shorts within the turn-to-turn coils and shows any imbalances between phases due to turn count differences, along with locating poor wire connections or contacts and finds open parallel coils. DC insulation resistance testing detects faults in ground wall insulation or motors that have already failed to ground. Weak
22
ground wall insulation (prior to copper¬to-ground failure) can only be found successfully with the HiPot tests. The ground wall insulation system consists of the magnet wires insulation, slot liner insulation, wedges, varnish and often phase paper. DC HiPot test should be performed at twice line voltage plus 1000 volts since motors will see voltage spikes of at least that level during each startup. HiPot testing is necessary to verify winding suitability for continued service. Surge testing detects faults in both inter-turn winding and phase-to-phase insulation systems. Turn-¬to-turn faults will not be seen by a megger or HiPot test. Potential faults can only be seen when the coils see more than 350 volts from turn-toturn or coil-to-coil, as described by Paschen’s Law.5 The typical mechanism of fault progression is a turn-to-turn short causing excessive heat and progressing within seconds or minutes to
copper to ground faults. Faults are much more likely to occur between turn-to-turn winding coils due to the added stress caused by bending and exaggerated during the winding process. The ground wall insulation is generally many times stronger and more capable of withstanding voltage spikes and other stresses.
Conclusions Integrating on-line and off-line testing into a Predictive Maintenance Program provides the technician with verification of his motor’s condition (See case studies below). Both technologies are necessary in order to have a complete picture of a motor’s health. Collecting both on-line and off-line data on a routine schedule allows for early warning of impending failures and opens the opportunity window for planned down time. Performing resistance, HiPot and surge testing along with dynamic testing provides the technician with a total picture of the motor’s condition and allows him to track its rate of decline. Modern test equipment includes enhanced and detailed reporting. Reports are easily generated, providing a written hard copy of test results and making diagnosing and comparing of data clearer and more accurate. Setting up and managing a program to monitor the motors within any facility is essential to insure the safe and continued operation and production of

the facility. In most cases, a properly managed and operated Predictive Maintenance Program will save a plant or facility much more than it will cost to implement, administer and manage.
Case Studies 1) At a large waste water treatment facility in Florida, fourteen identical motors were scheduled for predictive maintenance. These motors were 40 horsepower aerators for a large treatment tank and operated continuously. Static tests were performed on all fourteen and each received passing marks on all tests. When dynamic testing was complete, it was noted that thirteen motors were acting very similar running within expected parameters at approximately 85% load, while the fourteenth motor was running at just over 30% load. Further inspection revealed a sheared coupling on the motor running at reduced load. The operators had no way of detecting the problem and the location of these motors made visual inspection difficult. The dynamic testing found a problem that was costing the customer both in wasted kilowatt usage and production. 2) Twelve 60 horsepower pump/motors were tested at a large office building. Six were chilled water pump/motors and six were condenser water circulating pump/motors. All twelve were installed at the same time and ran continuously. Dynamic testing was performed one day on all twelve and all appeared to
be operating within expected parameters. The motors were shut down for a scheduled annual routine building maintenance and static testing was planned for the following morning. Resistance tests appeared normal on all, but two would not pass HiPot testing at the preset voltage. Three others failed the surge tests. The five motors were removed from service, disassembled and inspected. Two were found to be extremely dirty while three had no visual damage. All five were reconditioned, re-tested and replaced in service. The off-line testing prevented five potential catastrophic failures and allowed the customer to dictate the down-time.
