ONLINE PD SYSTEM

Partial discharges have been known to accelerate the ageing process. They cause erosion of insulating material and propagate through the treeing mechanism eventually bridging the electrodes and causing insulation breakdowns. While the Capacitance & Tan Delta tests indicate the presence of these discharges, this test records such pd signals. Online Partial Discharge test will be done using a Partial Discharge Analyser by using pre-installed couplers at rated voltage without disturbing the normal running condition of the generator.
