Quantitative current transformer check for leaks

Quantitative current transformer check for leaks

To verify the adequacy of winding to winding, and winding to ground insulation in each coil of the transformer under test. This transformer testing method also verifies the adequacy of all live-to-ground clearances in the transformer. SETUP: During this test, each winding is shorted out by connecting its bushings together.

    Feb 11, 2021Quantify the leakage current and then identify the source. One way of going about this is to use a leakage current clamp meter. These are very much like the clamp meters used for measuring load currents, but deliver significantly better performance when measuring currents below 5 mA. Most clamp meters simply wont register such low currents.
