Underground Cable Fault Distance Locator

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.

Underground cable fault distance locator.

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. The cable fault mainly occurs due to several reasons. Easy menu based operator guidance.

Underground cable fault distance locator circuit. 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 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. It is used to inject a high voltage dc surge about 25 kv into the faulty cable.

This paper proposes fault location model for underground power cable using microcontroller. Cable thumping for locating underground cable faults a cable thumper is basically a portable high voltage surge generator. This project uses the simple concept of. If you supply a sufficiently high voltage to the faulty cable the open circuit fault will break down creating a high current arc.
