Power quality monitoringdeviceTechnical requirements and purpose of:

1. Power quality monitoring deviceIt is a high-performance multifunctional power quality testing and analysis instrument. adoptDSP+ARM+CPLD Kernel,5.5 inchesLarge screen LCD(320×two hundred and fortylattice)Display screen, making the structure more compact, functionality more powerful, and display more convenient. Background management analysis, with rich functions and convenient operation.Measure and analyze the AC power quality supplied by the public power grid to the user end, including frequency deviation, voltage deviation, allowable three-phase voltage imbalance, and grid harmonics.

2. Applying wavelet transform to measure and analyze the harmonics of non-stationary time-varying signals;Measure and analyze the power quality of public power grids under different operating conditions of various electrical equipment;Load fluctuation monitoring: Regularly record and store the trend of changes in power parameters such as voltage, current, active power, reactive power, apparent power, frequency, phase, etc;Dynamic monitoring of power equipment adjustment and operation process helps users solve problems that arise during the adjustment and operation of power equipment.

3Test 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;The characteristics of portability, multi-parameters, large capacity, high accuracy, and the application of modern signal analysis theory makePower quality monitoring deviceIt can be widely used in fields such as power transmission and distribution, power electronics, and motor drive.
