Online monitoring of partial discharge (PD) in High Voltage (HV) power equipment needs to be monitored continuously for prediction of insulation life, replacement time and early indication of outages for reliable operation of the equipment. In this work, a new approach has been introduced for online monitoring of PD activity in a dielectric test cell with a needle-plate electrode configuration. The presented method has several advantages such as, it is immune to electromagnetic interference, good sensitivity, compact size and moreover it can also locate the sources of partial discharges in HV power equipment.
