Online 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.In case of Online PD the signals are collected from pre installed couplers using PD Analyzer.
Partial Discharge test will be done using Partial Discharge Analyser at normal running condition without disturbing the supply. 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.
Prognosys provides services like Online PD Coupler Installation ,Calibration,Periodic Data Acquisition & Assessment services
We provide Phase Resolved Partial Discharge (PRPD) analysis which will enable us to identify different types of PD
- Internal Discharges
- Surface Discharges
- Slot Discharges
