The conventionally used aid in cable fault testing and location is the cable test van. The van is installed with conventional cable measuring systems for quickly reaching the location of any cable fault. In 20 years that followed, over 2000 fault location vehicles were manufactured, more than half of which were intended for the former USSR.
The Murray loop bridge is a bridge circuit used for locating faults in underground or underwater cables. [1] [2] It has been used for more than 100 years [3] but is being replaced by the more precise Time-domain reflectometer. One end of the faulted cable is connected through a pair of resistors to the voltage source.
A cable locator or cable avoidance tool (CAT) is an instrument used for detecting the presence and approximate location of buried services in advance of undertaking excavation works. It aims to avoid accidents while excavating. [ 1 ]
Utility location is the process of identifying and labeling public utility mains that are underground. These mains may include lines for telecommunication , electricity distribution , natural gas , cable television , fiber optics , traffic lights , street lights , storm drains , water mains , and wastewater pipes.
In electric power distribution networks, a fault indicator is a device which provides visual or remote indication of a fault on the electric power system. Also called a faulted circuit indicator (FCI), [1] the device is used in electric power distribution networks as a means of automatically detecting and identifying faults to reduce outage time.

Underground cable locations are not always obvious, which can lead to unwary diggers damaging cables or being electrocuted. Operations are more difficult since underground cables' high reactive power produces large charging currents, making voltage control more difficult. Large charging currents arise due to the higher capacitance from ...
