A new approach to the diagnosis of solid insulation systems based on PD signal inference

A new approach to the diagnosis of solid insulation systems based on PD signal inference

The authors have developed digital instrumentation that can measure the amplitude, shape, phase, and number of pulses per cycle. Examples are given of results obtained from an induction motor, a hydrogenerator, a polymeric cable system with a defective joint, and a high-voltage current transformer.
