ETCG-V Transformer Core Grounding Current Tester
Power transformer is the most important electrical equipment in the power system.
Description
Power transformer is the most important electrical equipment in the power system. Once a fault occurs in operation it will cause serious consequences to the power system. The transformer core 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 core and the earth. The maximum current can reach tens of amperes which will cause partial overheating or even burnout of the core. It is the main means to ensure the safe operation and normal maintenance of transformers to discover the latent faults of transformers as soon as possible.
The transformer core grounding current tester can effectively solve these problems. It is widely used for leakage current testing of iron cores and clamps of transformers reactors and other electrical equipment in substations and power plants.
