ES4000 Power Quality Analyzer

ES4000 Power Quality Analyzer

The ES4000 Power Quality Analyzer is a three-phase, multi-function, intelligent, and simple comprehensive test instrument specially developed for on-site testing. It is easy to use, large LCD color screen display, high resolution, bilingual operation interface in Chinese and English, and vibration-proof structure shell.

It can measure 4 currents (ABC three-phase and neutral wire current),4 voltages (ABC three-phase voltage and neutral wire-to-ground voltage), the peak value of current and voltage, the maximum and minimum values within period of time, three-phase current Balance, short-term voltage flicker, transformer K factor, active power, reactive power, apparent power, power factor, displacement power factor, active energy, reactive energy, apparent energy, harmonic ratio, total harmonic distortion, display current and voltage real-time waveforms, phasor diagrams, and harmonic ratio bar graphs; dynamically capture instantaneous changes in voltage and current, monitor starting current, monitor various power parameters and generate alarm events list, record test data fora long time and generate trend curves Picture and other various functions.
