Mitigation of Power System Harmonics

IEEE 519-2014Mark HalpinNovember 2014What Has Stayed the Same?Most importantly, the overall philosophyUsers are responsible for limiting harmonic currentsSystem owner/operator are responsible for managing voltage qualityAll recommended limits apply only at the PCCExisting recommended limits are retainedSome new ones addedWhat Has Been Changed?Philosophy of changes Driven by 20 years of experience with 519-1992 and increased cooperation with IECMultiple changes related toMeasurement techniquesTime varying harmonic limitsLow voltage (
