| Abstract: | Aiming at the fault of 10 kV switch cabinet partial discharge, in order to get rid of the disturbance,judges accurately the discharge type and discharge point position, puts forward the method of using transientearth voltage (TEV), ultrasonic and ultra high frequency(UHF) makes combined detection, and makes verification in the practical fault locale. The result shows that this combined method is very effective in detectionand fix position of switch cabinet defection, improves the accuracy and efficiency of partial discharge faultdetection for switch cabinet. |
