HZZ-4000 Three-Phase Power Quality Tester
Introduction
HZZ-4000 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.
Basic function
★ Waveform real-time display (4 channels voltage/4 channels current).
★ True RMS values of voltages and currents.
★ The DC components of voltages.
★ Peak current and voltage values.
★ Minimum and maximum half-cycle RMS current and voltage values.
★ Phasor diagram display.
★ Measurement of each harmonic up to order 50.
★ Bar charts show harmonic ratios of current and voltage of each phase.
★ Total harmonic distortion (THD).
★ Active, reactive, apparent power, by phase and cumulative.
★ Active, reactive, apparent energy, by phase and cumulative.
★ Transformer K factor.
★ Power factors (PF) and displacement factors (DPF or COSΦ).
★ Short-term voltage flicker (PST).
★ Three phase unbalance(current and voltage).
