Introduction:

ETCR5000 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 cur-rent), 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.

Functions:

1．Waveform real-time display (4 channels voltage/4 channels current).

2．True RMS values of voltages and currents.

3． The DC components of voltages.

4．Peak current and voltage values.

5．Minimum and maximum half-cycle RMS current and voltage values.

6．Phasor diagram display.

7．Measurement of each harmonic up to order 50.

8．Bar charts show harmonic ratios of current and voltage of each phase.

9．Total harmonic distortion (THD).

10．Active, reactive, apparent power, by phase and cumulative.

11．Active, reactive, apparent energy, by phase and cumulative.

12．Transformer K factor.

13．Power factors (PF) and displacement factors (DPF or COSΦ).

14．Short-term voltage flicker (PST).

15．Three phase unbalance(current and voltage).
