TD3250 Portable Three-Phase Energy Meter Tester Application

☆ Calibration for Energy Meter Online

TD3250 Portable Three-Phase Energy Meter Tester Calibration for Energy Meter Online

• 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;

• 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.

• 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

TD3250 Portable Three-Phase Energy Meter Tester CT Transformation Ratio Calibration

• 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.

• 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.
