Transformer Core Earth Current Tester

Power transformer is the most important electric equipment in electrical power system.Once it failure in operation , it will bring serious consequence for power system .

The transformer core is single-point grounded in normal operation. If two or more than two point grounded, a current loop will form between iron core and the earth .The maximum current can reach dozens of amperes, which will cause local overheating and even burning of the iron core . To quickly detect the potential faults in transformer is the main means to ensure the safe operation and normal maintenance of transformer .

Transformer core ground current tester can solve all those problems effectively. It’s widely used for leakage current test between iron core of transformer or reactors and clamp in transformer substation , power station.

Transformer Core Earth Current Tester use caution method

During leakage current and current testing, the jaws must be fully closed, and the wire should be in the center of the jaws as much as possible during the testing process. Pay attention to clean the tongs after the test is completed

Head, maintain the meter; pay attention to connecting the test line during voltage test to avoid short-circuiting the tested line. After the voltage test is completed, the test wire should be removed from the wire under test first.

Pull it out from the meter to avoid electric shock.
