Cables are put underground to stay away from pointless obstruction. These force cables convey electrical force and when these cables are put underground it is extremely hard to decide the specific area of the deficiency happened. There are numerous elements or purposes behind a deficiency to happen as, for example, burrowing, tremor, development work and so forth. As it don't have a clue about the specific area of the issue happened to the cable the fixing procedure identified with that cable is troublesome. Underground cable framework is a most basic practice followed in the urban zones. This paper is expected to find the flaw in an underground cable lines from the base station to a precise area in kilometres. The framework identifies flaw with the assistance of potential divider organize laid over the cable. When a defect is found in a cable line, a voltage gets produced according to the resistors organize blend. This voltage is detected by the microcontroller and is refreshed to the client.
