Application Guide for Harmonic Mitigation


When electric power users need to correct power factor, or they desire to meet IEEE 519 they must first locate the source of harmonics.

If the electrical power system is in the design phase, gather any and all information regarding the harmonics that may be produced by non-linear loads.  A detailed one-line diagram including system voltages, transformer impedances, ASD Hp ratings, power rectifier kVA ratings, UPS kVA ratings and capacitor kVAr ratings is a good start to locating harmonics and the problems that may result.  Myron Zucker, Inc. has produced a "Power Factor Correction & Harmonic Filter Questionnaire" which guides the user through a series of questions to obtain the data listed above and requests a one-line diagram.

The same approach should be used for an existing system.  A harmonic study can be conducted to verify the system characteristics expected from the questionnaire or it can be done to determine the actual system characteristics. Myron Zucker, Inc. can provide assistance with both methods of locating harmonics.
