Power System Harmonics & Analysis


Harmonics are distortions to voltage and current waveforms that can create power quality problems in your facility's electric power system.  Harmonics are caused by non-linear electrical loads including: personal computers, test equipment, uninterruptible power supplies (UPS), fluorescent and LED lighting, power inverters, variable frequency drives (VFDs) and more.  As today's facilities incorporate more of these types of non-linear loads, harmonic issues are becoming an increasing problem.


High levels of harmonic distortion can cause the overheating of transformers, generators, motors, and feeder cables.  In addition, harmonics can cause the overloading of neutral conductors, flickering of lighting and equipment, and the nuisance tripping of circuit breakers and other protective devices.

PowerCom Corporation can perform a harmonic modeling analysis of your facility's electrical power system in addition to recommending mitigation techniques to reduce the harmonic levels and their effects.  We would field measure and record the harmonics that are present on your facility's electrical power system and create an accurate model of that system by incorporating the harmonic data that was gathered.  From there, we would analyze different mitigation scenarios and recommend cost effective solutions to reduce the harmonic levels on your electrical power system so they fall within IEEE or utility limits.
