GF4385 portable power quality analyzer is a low cost PQA carefully developed by GFUVE GROUP and specially designed for field test of three phase system, multi-functional and intelligent, concise man-machine operation.
It is easy to use, large LCD screen display, high resolution, English display, shock-proof shell structure and so on. simultaneously measure 4-channel current (I1 I2 I3 I4 three phase and neutral wire current) and 4-channel voltage (U1 U2 U3 U4 three-phase voltage and neutral line voltage to ground), the peak value of current voltage, maximum/minimum value over a period, three-phase unbalance factor, short-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.
