Product Description

It meets the whole requirements of GB/T1459～93 to test the virtual value, and positive ,reverse and zero sequence component of current and voltage
Measuring area: content of voltage harmonic, distortion factor of phase-angle and current voltage
Virtual value of current harmonics, distortion factor of phase-angle and total voltage harmonics
Range of measuring harmonics: fundamental wave -51times harmonics
Way of input signals: voltage, current, phase
Print: printed three-phase waveforms, statistic of the testing results, automatic printed three-phase results.

The key technical indexes:
