What is PD Levels Analysis by Sensor Type about?
The document analyzes over 272,000 partial discharge (PD) test results collected using Iris equipment up to 2011. The results are separated based on sensor type (capacitors or stator slot couplers) and cooling method (air or gas). Key findings include: - For air-cooled machines with capacitive sensors, 75% of results were below 172mV for machines rated under 12kV and below 239mV for 13-15kV machines. - Gas-cooled machines generally had lower PD levels than air-cooled. 75% of tests on gas-cooled machines op
