Description
Main Applications of the Power Quality Recorder
- Power Quality Recorder measures and analyzes AC power quality of public power grids at user terminals, covering frequency deviation, voltage deviation, voltage fluctuation and flicker, permissible three-phase voltage unbalance and grid harmonics.
- Adopt wavelet transform to measure and analyze harmonics of non-stationary time-varying signals.
- Power quality testing monitors and assesses the impact of various electrical equipment on public grid power quality under different operating conditions.
- Load fluctuation monitoring: regularly record and store the variation trends of electrical parameters such as voltage, current, active power, reactive power, frequency and phase.
- Realize dynamic monitoring during commissioning and operation of power equipment, assisting users in troubleshooting issues arising from equipment adjustment and put-into-service.
- Test and analyze the causes of power system faults, including circuit breaker operation anomalies, transformer overheating, motor burnout and incorrect operation of automatic devices.
- Measure dynamic parameters of reactive power compensation and filtering devices in power systems, and conduct quantitative evaluation on their functions and technical specifications.
- Power quality testing, featuring online operation, multi-parameter measurement, large storage capacity, high precision and adoption of modern signal analysis theories, is widely applied in power transmission & distribution, power electronics, motor drive and other fields.
