Partial Discharge (PD) Test of Transformer | Importance & Methods
What is Partial Discharge in Transformers? Partial Discharge (PD) is a localized electrical discharge that occurs within the insulation system of a transformer. It does not completely bridge the space between conductors but indicates early-stage insulation deterioration. Over time, these discharges can cause insulation breakdown, resulting in power failure or costly transformer damage. The Partial […]
