Portable PQ Analyzer

Model: PQA-400
Current electric power applications, due to more and more large power equipment, the complex power grid system and the fault is becoming more and more complex, more and more difficult to troubleshoot, and due to the development of the industry of power grid power quality request more and more is also high. For this purpose, we provide this kind of measuring and analyzing instrument PQA-400 which can eliminate complex power system faults more quickly and accurately, and monitor and maintain power quality parameters more comprehensively and systematically.
The Portable PQ Analyzer PQA-400 is a highly intuitive and advanced portable 3-phase analyzer. IP54 weatherproof enclosure is designed for outdoor operation. The
unit is robust enough to remain recording outdoors.
The Portable PQ Analyzer PQA-400 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.
The PQA-400 can record for extended periods of time because of its massive memory. It utilizes a built-in 2G memory card which makes expanding the memory easy. The recorded data can be viewed on the LCD display of PQA-400. The data also can be transferred to the PQ analysis software via USB cable.

Technical Data

The Portable PQ Analyzer PQA-400 is the ideal tool for testing power quality in any environment. It makes the testing more efficient, and enables the operator to quickly and easily analyze test results.
