Underground Cable Fault Distance Locator

Pulse echo impulse current and decay method for all types of fault conditions.

Underground cable fault distance locator.

If you supply a sufficiently high voltage to the faulty cable the open circuit fault will break down creating a high current arc. The aim of this project is to determine the distance of underground cable fault from base station in kilometers. It is used to inject a high voltage dc surge about 25 kv into the faulty cable. To overcome this difficulty here is a solution namely underground cable fault distance locator helpful to discover the fault cable location in underground.

5 improved public safety. This paper proposes fault location model for underground power cable using microcontroller. Underground cable fault distance locator circuit. Easy menu based operator guidance.

This project uses the simple concept of. Cable fault per locator reflectometer t 510 is used for location of distance to the fault in underground power cable from lt to ht. 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.
