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 normally operating transformer is grounded at a single point. If two or more points are grounded simultaneously, a current loop will be formed between the iron core and the ground, with a current of up to tens of amperes, which will cause local overheating or even burning of the iron core. Detecting latent faults in transformers as soon as possible is the main means of transformer operation and normal maintenance.

The transformer core grounding current tester can effectively solve these problems. Widely applicable for leakage current testing of iron cores and clamps in electrical equipment such as transformers and reactors in substations and power plants.
