1. It can display single-phase voltage and current waveforms and simultaneously display three-phase voltage and current waveforms.
2. All test interfaces have screen lock function to facilitate users to read and analyze data.
3. Load fluctuation monitoring: measure and analyze the fluctuations of various electrical equipment on the power quality of the public grid caused by different operating states.
4. Regularly record and store the trends of power parameters such as voltage, current, active power, reactive power, apparent power, frequency, and phase.
5. Dynamic monitoring of power equipment adjustment and operation process to help users solve problems in the process of power equipment adjustment and commissioning.
1. Measure and analyze the quality of AC power supplied by the public power grid to the user. Measurement and analysis: frequency deviation, voltage deviation, allowable unbalance of three-phase voltage, and power grid harmonics.
2. Apply wavelet transform to measure and analyze the harmonics of non-stationary time-varying signals.
3. Measure and analyze the power quality of the utility grid under different operating states of various electrical equipment.
4. Load fluctuation monitoring: regularly record and store the changing trends of power parameters such as voltage, current, active power, reactive power, apparent power, frequency, and phase.
5. Dynamic monitoring of power equipment adjustment and operation process to help users solve problems in the process of power equipment adjustment and commissioning.
6. Test and analyze the failure causes such as circuit breaker action, transformer overheating, motor burnout, and automatic device malfunction in the power system.
7. Test and analyze the dynamic parameters of reactive power compensation and filtering devices in the power system and make quantitative evaluations of their functions and technical indicators.
