Partial Discharge Analysis Ultrasonic Techniques to Evaluate Partial Discharge in Electrical Machinery

Partial discharges are small electrical sparks that occur within the electric insulation of switchgear, cables, transformers, and windings in large motors and generators. Partial discharge analysis is a proactive diagnostic approach that uses partial discharge (PD) measurements to evaluate the integrity of this equipment. Each discrete PD is a result of the electrical breakdown of an air pocket within the insulation. PD measurements can be taken continuously or intermittently and detected on-line or off-line. PD results are used to reliably predict which electrical equipment is in need of maintenance.
