Product Description

High Accuracy Multi-functional Electric 3 Phase Energy Meter Calibration Device



 
Product Description

I.Introduction


The handheld three-phase energy meter field calibrator is a series of Our company's products, and is a product integrated with low-voltage energy meter calibrator and low-voltage metering device calibrator. It can not only measure high-voltage energy meter and wiring, but also measure the integrated error of low-voltage measuring devices, as well as TA transformation ratio, TV and TA secondary load. Such an instrument is equivalent to several instruments.
