HZCR-5000 Three Phase Digital Power Quality Analyzer

3 Phase Power Quality Analyser

Huazheng Electric HZCR-5000 Three Phase Digital Power Quality Analyzer

HZCR-5000 Power Quality Analyzer is a comprehensive test instrument carefully developed by our company and specially designed for field test of three phases, multi-functional and intelligent, concise man-machine operation. It is easy to use, large LCD screen display, high resolution, interface in both Chinese and English, shock-proof shell structure and so on. Can simultaneously measure the 4-channel current (ABC three phase and neutral wire current), 4-channel voltage (ABC three-phase voltage and neutral line voltage to ground), the peak value of current voltage, maximum/minimum value over a period, three-phase imbalance factor, short-time voltage flicker, transformer K factor, active power, reactive power, apparent power, power factor and displacement power factor, active power, reactive power, apparent power, total harmonic distortion and harmonic, etc; Display real-time waveform, harmonic ratio bar charts of current voltage; Dynamically capture instantaneous change of voltage current, monitoring starting current, monitoring the power parameters and generate the alarm list, generate the trend chart for a long time record test data.

In the current power applications, more and more large power equipment, power grid fault have become more and more complex, with development of the industry, it put forward high request more and more to quality that electric energy. We provide this power quality analyzer for that, which you can troubleshoot of complex power system more quickly and accurate, and monitoring and maintenance of power quality parameters more comprehensive and systemic.
