Use the fixed-point meter to accurately locate the fault point, connect the high-voltage equipment according to the fixed-point discharge method, and determine the degree of boosting according to the nature of the cable and the withstand voltage level of the cable. Accurate detection of cable fault points. In order to protect the instrument, please remove the main engine and inductance when fixing the point, and use the pointing instrument to accurately locate the fault point. Connect the high-voltage equipment by the fixed-point discharge method, and determine the degree of boosting according to the nature of the cable and the withstand voltage level of the cable.
Accurate detection of cable fault points. In order to protect the instrument, please remove the host, inductance and water resistance, etc., and connect as shown in Figure 7. If the fault point is very close to the test end, especially at the test end of the cable, when using Figure 7 to locate, because the discharge sound of the ball gap is louder than the discharge sound of the fault point, it is difficult to distinguish the true and false sound. If necessary, the high-voltage equipment can be moved to the other end to locate.
