Power quality monitoringdeviceWhat are the functional features?

1. Component measurement and voltage imbalance analysis.It can measure the imbalance of voltage and current, as well as the amplitude and phase of zero sequence, positive sequence, and negative sequence, and display the phase diagram of voltage and current. Monitoring and recording of frequency fluctuations in the power system，The frequency measurement accuracy is0.001Hz, frequency range from42.5HzContinuous to57.5HzMonitor the frequency of the power system online, and if the frequency exceeds the limit, timely alarms and records can be given.

2. Harmonic analysis.Monitoring the measured signalsixty-threeSubharmonic components, including1-50Each time, the harmonic distortion rate, total harmonic distortion rate, harmonic phase angle, and inter harmonic meet the national standardsGB/T14549和IEC61000-4-7Requirements for testing harmonics in public power grids.It can continuously monitor whether the power quality meets relevant standards. Through software, different exceeding conditions can be set, and the exceeding energy parameters can be counted and recorded, with a time resolution of up to1ms。

3. Flashover analysis.The flicker effect caused by rapid voltage changes caused by impulsive power loads (such as steelmaking arc furnaces, arc welding machines, etc.) at public power supply points can easily cause eye fatigue, discomfort, and even emotional irritability.Equipped with voltage flicker monitoring function, in line withGB/T12326-2008Standards.Capable of capturing waveforms of all voltage and current channels and analyzing interference sources. Harmonic components exceeding the standard, distortion rate exceeding the standard, voltage effective value exceeding the standard, short circuit faults, etc. can all initiate voltage waveform and fault recording to capture subtle changes in voltage waveform.
