Underground Cable Fault Distance Locator

The cable fault mainly occurs due to several reasons.

Underground cable fault distance locator.

Pulse echo impulse current and decay method for all types of fault conditions. Cable thumping for locating underground cable faults a cable thumper is basically a portable high voltage surge generator. 3 less fault occur in underground cable 4 underground cable fault location model are applicable to all types of cable ranging from 1kv to 500kv other types of cable fault such as short circuit fault cable cuts resistive fault sheath faults water trees partial discharges. This project uses the ohms law concept when a low voltage dc is applied to the feeder end through a series resistor then the current would differ based on the location of fault occurred in the cable in case is there any short circuit occurred from line to ground then the voltage across series resistor alters accordingly then it is fed to an.

Underground cable fault distance locator circuit. 5 improved public safety. This project uses the simple concept of. Easy menu based operator guidance.

To overcome this difficulty here is a solution namely underground cable fault distance locator helpful to discover the fault cable location in underground. Cable fault per locator reflectometer t 510 is used for location of distance to the fault in underground power cable from lt to ht. This paper proposes fault location model for underground power cable using microcontroller. It is used to inject a high voltage dc surge about 25 kv into the faulty cable.
