Transformer Routine Test - Partial Discharge MeasurementGet Price!
12/4/2018· In addition to the measured partial-discharge level, the below conditions should also be considered in transformers: Partial-discharge start and cease voltages are above the operating voltage. Depending on the test period, partial-discharge level stays approximately stable. Increasing the test voltage causes almost no partial-discharge level.
Partial discharge test of transformerGet Price!
6/17/2017· Partial discharge test of transformer. Partial discharge test of transformer is very important test That helps us to detect any defect in transformer insulation Partial discharge occurs as a result of the presence of moisture in liquid insulators or the presence of cavity in insulation due to defects in the manufacture of solid insulators.. To see full details about transformer testing.
