Underground fault locating is the process of identifying the location of faults or faults in underground electrical power distribution or transmission systems. The objective is to find the source of the fault, so it can be repaired to restore power to the affected customers. The methods used to locate faults include the use of high-impedance fault locators, time-domain reflectometry (TDR), and high-frequency transient electromagnetic (HF-TEM) techniques. The selection of the appropriate method depends on the type of fault and the characteristics of the electrical system.
