Partial Discharge Analysis
Partial discharges have been known to accelerate the aging process. They cause erosion of insulating material and propagate through treeing mechanism eventually bridging the electrodes and causing insulation breakdowns. While the Capacitance & Tan Delta tests gives us the indication of presence of these discharges, this test records such pd signals.
Partial Discharge test will be done using Partial Discharge Analyser by applying voltage as applied for tan delta test. PD Analyser system is used for partial discharge test that includes analysis software that gives discharge patterns for defect identification and also quantifies the partial discharge in the winding for trend analysis.
We provide Phase Resolved Partial Discharge (PRPD) analysis which will enable us to identify different types of PD.
