The multifunctional three-phase electric energy meter on-site calibrator has synchronous power frequency parameter measurement functions. It can calibrate various active and reactive energy meters on-site without power outage or disconnection, and automatically identify incorrect wiring of energy meters. When equipped with current clamps of various specifications up to 2000A, it can measure the comprehensive error of energy metering cabinets, current transformer ratio, and power quality (harmonics). It is a high-precision testing instrument that integrates energy meter calibration, electrical parameter testing, and detection of power quality issues such as waveform distortion, voltage fluctuations and flicker, and three-phase unbalance in the power grid.
Uses of the multifunctional three-phase electric energy meter on-site calibrator:
1. Electrical parameter measurement (U/I/Φ/P/Q/S/PF/Hz);
2. Discrimination of inductive and capacitive circuit load characteristics;
3. Detection of power consumption/power testing of electrical equipment;
4. Single-phase and three-phase energy error calibration;
5. Comprehensive measurement of low-voltage metering devices;
6. Load curve recording and online monitoring of load fluctuations;
7. Can be equipped with large current clamp meters for data collection of power line loss management;
8. Measurement of power grid power quality;
9. Household meter wiring inspection, anti-theft electricity inspection.
