Product Details

■ Product Overview

Power transformers are the most critical electrical equipment in power systems; any fault during operation can have severe consequences for the system. In normal operation, the transformer core is grounded at a single point. If the core is grounded at two or more points simultaneously, a current loop will be established between the core and earth, with peak currents potentially reaching several tens of amperes, leading to localized overheating and even burnout of the core. Prompt detection of latent transformer faults is essential for ensuring safe operation and routine maintenance.

The transformer core grounding current tester effectively addresses these issues. It is widely used in substations and power plants for measuring leakage currents in the cores and clamps of transformers, reactors, and other electrical equipment.
