A new method for judging breakpoints of wires and cables by the cable fault location system The specific methods of the cable fault location system: 1. Suspend the conductor core of the cable to ensure that it will not lead to road and electric shock accidents; , equipment, etc.) farther away; 2. Select a sound insulation core in the cable, connect the 220VAC phase wire (live wire), and not the ground wire; 3. If you use an induction pen, touch your finger on the induction contact on the pen, and in It can be clear whether the test pen is normal outside the insulating layer of the charged body. If you use a digital multimeter, set the multimeter to 20 or 200mV, put a thin plastic insulating sleeve on the red test lead, and hold the black test lead with your hand; test outside the insulating layer of a clear charged body, and read; then remove it from the The charged body is farther away, and read; compare the difference between the two readings, usually there should be a higher reading on the charged body, such as 0.4mV, and a lower reading, such as 0.15mV far away from the charged body; remember this feature, you can Start testing. 4. Test along the cable close to the cable. When it is found that the indicator light of the induction pen is dimmed, or the reading of the multimeter drops significantly, the change is the breakpoint.
