Power quality monitoringdeviceWhat are the commonly used functions?

1. Power system monitoring, alarm, and recording. Multiple data monitoring alarms and records, frequency limit exceeding alarms, three-phase voltage harmonic exceeding alarms, three-phase current harmonic exceeding alarms, voltage exceeding and below the line alarms, total voltage distortion rate alarms and voltage imbalance alarms, and real-time monitoring alarms and records of various parameters.

2. Harmonic analysis. Monitor the 2-63 harmonic components of the measured signal, including the harmonic distortion rate of three-phase voltage 2-63, three-phase current 2-63, three-phase voltage inter harmonic, three-phase current inter harmonic, three-phase voltage total harmonic distortion rate, and three-phase current total harmonic distortion rate. Meet the testing requirements of national standard GB/T14549-1993 for harmonics in public power grids.

3. Voltage fluctuations and fault recording.Online monitoring device for power qualityCan capture the waveform of all voltage channels crossing the line. Voltage effective value exceeding the standard, short circuit fault, etc. can initiate voltage transient waveform recording to capture subtle changes in voltage waveform.

4. Component measurement and voltage imbalance and deviation analysis.Power quality monitoring deviceIt can measure the imbalance of voltage and current, as well as the amplitude of zero sequence, positive sequence, and negative sequence, voltage deviation, and display the phase diagram of voltage and current.
