Insulation System Characterization of High Frequency High Voltage Transformers

This work reports the use of the Partial Discharge (PD) measurement technique as a tool for the investigation of High Frequency/High Voltage Pulsed (HF/HVP) transformers for motorsport application. PD technique is successfully applied to monitor the status of the internal insulation of these devices. Insight about the ageing and failure mode of the internal insulation system is obtained. PD technique proves to be a valuable diagnostic tool for HF/HVP transformers.
