Abstract : Finding and designing the method for
determining type and exact location of faults in
power system has been a major subject for system
protection. This paper evaluated 3-ph
underground distribution cable fault and
researched innovative techniques for diagnosing
failing underground power distribution cables. In
this paper, a technique for detecting faults in
underground distribution system is presented. A
HV surge tester is used to generate spark at fault
position which produces noise and vibrations in
fault site set and exact fault point is located by
detecting the fault.The surge wave device is
basically high voltage pulse generator consisting of
a dc power supply, high voltage capacitor. The
power supply is used to charge the capacitor into
the cable under test.If the voltage is enough to
break the fault, the energy stored into the
capacitor is suddenly discharged into the cable
producing sound and vibrations which is also
called “thump” and this device is called as voltage
thumper and is called as shock discharge method.
The result is found that the proposed technique
provides satisfactory result and will be very useful
in the development of power systems protection
scheme.
