Features:
1.The total harmonic distortion rate of voltage and current can be measured;
2. can measure short-time flicker (PST), long-term flicker (PLT), voltage fluctuations;
3. can measure positive sequence voltage, negative sequence voltage, zero sequence voltage, voltage imbalance;
4.can measure positive sequence current, negative sequence current, zero sequence current, current unbalance degree;
5. transient parameter measurement function, with voltage sudden rise and sudden drop event recording function, while automatically start the wave recording function, the occurrence time of the event and the actual waveform of five cycles before and after the event is recorded;
6. with oscillographic function, can display the voltage and current size and distortion in real-time waveform, and can scale the voltage and current waveform on the instrument; With waveform factor calculation function;
7. hexagonal diagram display function, can carry out the vector analysis of the metering circuit and the protection device circuit, and check the wrong wiring of the metering device; In the three-phase three-wire connection mode, 48 kinds of connection modes can be automatically judged; Automatic recharge power calculation function, convenient for users to calculate the recharge power of users with wiring problems.
8. the selection of tongs can be used for low voltage current transformer ratio and Angle difference measurement;
