| Abstract: | A partial discharge sensor is designed in switch cabinet which is used to acquire the transient voltage to earth （TEV） generatored in switch cabinet PD. The system function consists of capacitive coupling, filtering, and amplification and down clock. It is with the excellence of low noise, high sensitivity and wide dynamic range, etc. The test shows that the sensor can acquire switch cabinet partial discharge from the transient voltage to earth reliably. |
