Should be avoided Tested wire at the center of clamp. (23±2)°C -10°C~ 40°C Fast delivery I 24-hour customer service I customizable 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. Phase-to-neutral voltage: All parameters Phase-to-phase voltage: True RMS phase-to-phase voltage Current: True RMS current Network frequency: All parameters Phase shift: Active power and active energy Reactive power and reactive energy Harmonic: All parameters Voltage unbalance: All parameters Working voltage of device: All parameters External electric field, magnetic field: AI1 parameters Test position: Measured related parameters of current Environment temperature: All parameters Relative humidity: All parameters # Waveform real-time display (4 channels voltage/4 channels current). # True RMS values of voltages and currents. # 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. # Power factors (PF) and displacement factors (DPF or COScp). # Short-term voltage flicker (PST). # Three phase unbalance(current and voltage).
