Statistical Analysis and Discharge Type Identification of Partial Discharge Pulse Parameters of Oil-Paper Insulation Based on Ultra-wideband

The effective measurement frequency band of the traditional pulse current method is up to 1MHz, which causes the loss of the main energy frequency band information of the partial discharge pulse signal. In view of this, an ultra-wideband partial discharge pulse measurement system with an effective measurement frequency band of 30kHz-50MHz is designed. The system is used to measure the discharge si...
