Product Details

Common functions of online power quality monitoring instrument

Monitoring, alarm and recording of power system
Multiple data monitoring, alarm and recording, frequency limit exceeding alarm, three-phase voltage harmonic exceeding alarm, three-phase current harmonic exceeding alarm, voltage exceeding upper and lower limits alarm, total voltage distortion rate alarm and voltage imbalance alarm, etc. Real time monitoring, alarm and recording of various parameters.

harmonic analysis
Monitor the 2-63rd harmonic components of the measured signal, including the distortion rates of the 2nd to 63rd harmonics of the three-phase voltage, the distortion rates of the 2nd to 63rd harmonics of the three-phase current, the harmonics between the three-phase voltage, the harmonics between the three-phase current, the total harmonic distortion rate of the three-phase voltage, and the total harmonic distortion rate of the three-phase current. Meet the testing requirements of GB/T14549-1993 for harmonics in public power grids.

Voltage fluctuations and fault recording
The online monitoring device for power quality can capture the waveform of all cross line voltage channels. Voltage transient waveform recording can be initiated to capture subtle changes in voltage waveform, such as exceeding the effective voltage value and short circuit faults.

Component measurement and analysis of voltage imbalance and deviation

The online monitoring device for power quality 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.
