Data is being organized .....

★ Fully functional, it not only meets the testing requirements of various CT excitation characteristics such as ratio, polarity, secondary winding resistance, secondary load, ratio difference, and angle difference, but also can be used for testing the excitation characteristics, ratio, polarity, secondary winding resistance, etc. of various PT electromagnetic units.

★ Automatically provide inflection point voltage/current, 10% (5%) error curve, accuracy limit factor (ALF), instrument safety factor (FS), secondary time constant (Ts), remanence coefficient (Kr), and other CT and PT parameters.

★ The test meets various transformer standards such as GB1208 (IEC60044-1), GB16847 (IEC60044-6), GB1207, etc., and automatically selects which standard to test according to the type and level of transformer.

Based on the principle of low-frequency testing, it can handle CT testing with inflection points up to 30KV.

★ One click completion of CT direct resistance, excitation, transformation ratio, and polarity testing, using the same wiring method.

★ Easy to carry, device weight<8.2kg.
