Abstract:
With the current economic expansion, power demand is continually growing. Distribution lines
making up most of the power system are crucial for distributing power from the power plant to the
consumer. Power distribution can be done via overhead lines or underground cables, but there are
instances where a combination of both is utilized. These lines are susceptible to faults like any other
electrical system, primarily brought on by moisture in the paper insulation, cable brittleness, or flaws in
splices or other accessories. Due to the low power distribution efficiency caused by these faults, there is a
significant annual power loss. The secret to improving the dependability and ideal performance of the
system is discovering and developing new techniques to pinpoint the type of fault. This paper examines
numerous methods for classifying faults in a jointed overhead-underground distribution line.
