ACCESSING %THD FUNCTIONS

5.3Accessing %THD Functions

Harmonic Measurement readings are available on the EPM 5300P meter. The EPM 5300P displays 6 parameters of total harmonic distortion. It measures harmonic waveforms and %THD for voltage phases A-N, B-N and C-N, and current phases A, B and C. Measurement capability reaches the 31st harmonic order. All readings are faceplate accessible.
