3. Application

 

☆ Calibration for Energy Meter Online

 

1. Support direct measurement for 10 V~480 V, 0.05 A~12 A, and current clamp measurement for 0.1 A~120 A; electric energy metering;
2. Application 1 (direct measurement of current): applicable to the calibration of single-phase / three-phase voltage source, current source, power source, etc. in the laboratory or on site.
3. Application 2 (use clamp for current): It is not necessary to cut off the circuit, just clamp the current line into the jaw, and you can real-time measuring online.

 

☆ CT Transformation Ratio Calibration

 

1. CT transformation ratio test: use large current clamp for primary signal of CT, and with small current clamp for secondary signal of CT; Calculate the transformation ratio of CT and the phase relationship of primary/secondary current. Help judge if the CT runs well.
2. Note: Standard configuration for 5 A clamp, which can be used for the secondary side, If user need other clamps should indicate the optional specification in the order.
