On site verification of current transformers does not require standard current transformers, current boosters, load boxes, voltage regulation control boxes, or high current wires. Simple testing wiring and operation are used to achieve the verification of current transformers, reducing work intensity and improving work efficiency, making it convenient to carry out on-site transformer verification work; Quick, simple, precise, and convenient.

1. The interface is friendly and beautiful, with a Chinese graphical interface. The panel comes with a built-in printer that can print curve graphs and test data at any time
2. The testing is simple and convenient, with one click completion of CT direct resistance, excitation, transformation ratio, and polarity testing. In addition to load testing, all other CT tests use the same wiring method
4. Based on the principle of low-frequency testing, it can cope with CT testing with inflection points up to 40KV or above
