Power quality monitoringdeviceThe main purpose of:

Measurement and analysis of the AC power quality supplied by the public power grid to the user's receiving end. The measurement and analysis indicators include power supply frequency deviation, power supply voltage deviation, power supply voltage fluctuation and flicker, allowable imbalance of three-phase power supply voltage, and grid harmonics Applying wavelet transform to measure and analyze the harmonics of non-stationary time-varying signals. Measure and analyze the impact of various electrical equipment on the power quality of the public power grid under different operating conditions.Load fluctuation monitoring: Regularly record and store the trend of changes in power parameters such as voltage, current, active power, reactive power, frequency, phase, etc. Dynamic monitoring of power equipment adjustment and operation process helps users solve problems that arise during power equipment adjustment and operation. Test and analyze the causes of faults such as circuit breaker action, transformer overheating, motor burning, and automatic device malfunction in the power system. Test and analyze the dynamic parameters of reactive power compensation and filtering devices in the power system, and quantitatively evaluate their functions and technical indicators.
