Underground Cable Fault Detection Method

Here the electromagnetic field already present on the utility is detected with the help of a receiver or detector. 1000 joules energy on 5 10 20 kv range. Use of the arc reflection method combined with a high capacitance surge generator and state of the art pinpointing devices for underground cable fault locating will find faults in less time and with less risk of damaging good cable than classical techniques.

Two of the popular techniques are the murray and varley loop tests for locating faults in underground cables this article explains about few other popular techniques for locating faults in underground cables viz.

Underground cable fault detection method.

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. Finding the location of an underground cable fault doesn t have to be like finding a needle in a haystack. Underground cable fault distance locator circuit. High voltage for pressure testing of the underground cables to find out faulty phase and the breakdown voltage with leakage current.

Surge generator generates d c. There are many locating methods coupled with new detection technologies that make this task much easier and less time consuming. But finding the exact location of the cable fault needs special techniques. Cable detection or fault finding can be done via two methods.

In order to identify the faults in the cable we need to develop special methods which will be discussed in this article. In this method you inject a specific frequency signal with help of a transmitter and then race it back with a receiver. The surges produced help in pinpointing the fault and tracing the route of the cable when used with acoustic fault locator. Before we discuss fault detection methods we shall study the various types of faults occurring in underground cables and their causes.

Finding the type of a fault in underground cables using a megger should not be a difficult task.
