Underground Cable Fault Distance Locator

They are any defect inconsistent insulation failure weakness of the cable and breaking of the conductor.

Underground cable fault distance locator.

Underground cable fault distance locator circuit. To overcome this difficulty here is a solution namely underground cable fault distance locator helpful to discover the fault cable location in underground. Easy menu based operator guidance. Pulse echo impulse current and decay method for all types of fault conditions.

Cable fault per locator reflectometer t 510 is used for location of distance to the fault in underground power cable from lt to ht. It is used to inject a high voltage dc surge about 25 kv into the faulty cable. The cable fault mainly occurs due to several reasons. This project uses the simple concept of.

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. 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. Cable thumping for locating underground cable faults a cable thumper is basically a portable high voltage surge generator.
