Integrated Power Quality Test Instrument

Primary Usage

1 Assessing the quality of alternating current electrical power supplied to customers from the public grid, the analysis includes: frequency deviation, voltage deviation, voltage fluctuations and flicker, permissible unbalance degree of three-phase voltage, and grid harmonics.

2 Harmonic measurement and analysis of non-stationary time-varying signals using wavelet transform.

3 Analyze the power quality of the public power grid influenced by various electrical equipment under different operating conditions.

3 Load Fluctuation Monitoring: Timely recording and storage of the variation trends of electrical parameters such as voltage, current, active power, reactive power, apparent power, frequency, and phase.

4 Dynamic monitoring of power equipment adjustment and operation processes helps users resolve issues that arise during the adjustment and commissioning of power equipment.

5 Test the causes of faults in power systems, such as circuit breaker operation, transformer overheating, motor burnout, and incorrect operation of automatic devices.

6 Test and analyze the dynamic parameters of reactive compensation and filtering devices in power systems, and provide a quantitative evaluation of their functions and technical specifications.

7 The portable, multi-parametric, high-capacity, high-precision, and modern signal analysis theory applications make the electric power quality analyzer widely applicable in fields such as power transmission and distribution, power electronics, and motor driving.
