1. Measurement and analysis of 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;Power quality monitoring仪Analyze the power quality of public power grids under different operating conditions of various electrical equipment; Test and analyze the causes of faults such as circuit breaker action, transformer overheating, motor burning, and automatic device malfunction in the power system.

2. 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; Applying wavelet transform to measure and analyze the harmonics of non-stationary time-varying signals; 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.

3. Dynamic monitoring of power equipment adjustment and operation process, helping users solve problems that arise during the adjustment and operation of power equipment; The characteristics of portability, multi-parameter, large capacity, high accuracy, and the application of modern signal analysis theory make GD-PQ1100 widely applicable in fields such as power transmission and distribution, power electronics, and motor drive.
