PRPD Pattern Overview

Dr. Kay RETHMEIER, OMICRON electronics, 2010-05-10

This is a short summary about PRPD pattern. These patterns strongly depend on the PD filter settings

chosen during PD measurement and may differ from other examples to be found in literature.

Corona Discharges on HV Potential（电晕放电）

Starting with a single PD pulse at 270° of the test voltage, developing in both directions when increasing

the test voltage level. Only discharges in negative half cycle, similar amplitude, independent from test

voltage level. With test voltage level much about PDIV there will be additional pulses in the positive test
