Power transformer is an important electrical equipment in the power system. Once a fault occurs during operation, it will cause serious consequences to the power system. The iron core of a transformer in normal operation is grounded at a single point. If two or more points are grounded at the same time, a current loop will be formed between the iron core and the earth, and the current can reach dozens of amperes, which will cause local overheating of the iron core or even burn. Finding the latent fault of the transformer as soon as possible is the main means to ensure the safe operation and normal maintenance of the transformer.

YNXDL-H transformer core ground current tester can effectively solve these problems. It is widely used to test the leakage current of iron cores and clamps of electrical equipment such as transformers and reactors in substations and power plants.
