The principle of the bridge method for cable fault location is as follows: Short-circuit the faulty phase and the non-faulty phase of the cable under test. Connect the two arms of the bridge to the faulty phase and the non-faulty phase respectively. Adjust an adjustable resistor on each arm of the bridge to balance it. Using the proportional relationship and the known cable length, the fault distance can be calculated. The advantages of the bridge method for cable fault location are its simplicity and accuracy meeting the requirements of on-site engineering testing. It is particularly convenient for measuring two-phase short-circuit faults in cable lines. Using the Murray bridge to locate the breakdown point is a classic method, convenient and accurate. The bridge method is based on the premise that the resistance of the conductor (or shielding layer) is uniform and proportional to its length. The following figure shows a typical application:
