Product Details
GDTX-II Transformer Core Grounding Current Tester
1、 Product Overview
Power transformers are the most important electrical equipment in the power system. Once a fault occurs during operation, it will cause serious consequences to the power system. The 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 core and the ground, with a maximum current of several tens of amperes, which will cause local overheating or even burning of the core. Discovering potential faults in transformers as soon as possible is the main means to ensure safe operation and normal maintenance of transformers.
GDTX-II Transformer Core Grounding Current TesterCan 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.
