Introduction to Portable Three phase Energy Meter Field Calibration Instrument

CJJL-860 Three phase Energy Meter On site Calibration Instrument, also known as Three phase Multi functional Electricity Inspection Instrument, has the function of synchronously measuring power frequency parameters. It can calibrate various active and reactive energy meters on site without cutting off power or disconnecting wires, and automatically identify incorrect wiring of energy meters; After adapting to various specifications of current clamps ranging from 5A to 2000A, the comprehensive error, current transformer ratio, and power quality (harmonics) of the energy metering cabinet can be measured. It is a high-precision testing instrument that integrates the verification of energy meters, electrical parameter testing, and detection of waveform distortion, voltage fluctuations and flicker, and three-phase imbalance in the power grid. This product is suitable for use in departments such as electricity metering and anti-theft in the power industry, as well as internal electricity management departments such as chemical, metallurgical, mining, railway, and property management
