What is the bridge method for cable fault location? A: This is the classic method of ranging for power cables. This method is relatively simple, but it is necessary to know the cable length and other data in advance, and it is only suitable for low resistance and short circuit faults. However, in actual operation, the fault is often a high-resistance and flashover fault. Because the fault resistance is high, the bridge current is small, so the general sensitivity meter is difficult to detect.
