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.

Power, distribution and instrument transformers . Partial discharge testing is an essential, proven tool that can locate and identify flaws in the insulation of cables, bushings, windings, tap changers and a myriad of other assets and accessories.
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 Testing for Power TransformersGet Price!
Value of Partial Discharge Testing for Power Transformers PD measurement is a fundamental tool used to assess the condition of oil-filled or cast resin power transformers. This unique on-line method can directly assess the solid insulation of power transformers and detect the deterioration of inter-turn insulation, disks insulation, HV to LV.
