Offline vs. Online Partial Discharge Testing by cubartur is a document available to read on EtoBox.
The document compares off-line and on-line partial discharge (PD) testing of the insulation condition for seven large motors. Off-line PD measurements were performed using a commercial PD detector on epoxy-mica couplers installed in the motors. On-line PD pulses from sensors were measured during normal operation using a turbine generator analyzer and PD analyzer. The off-line and on-line test results from the different instruments showed internal discharges in the groundwall insulation and were indicative o
