Power system equipment are very expensive, and so a very
large capital investment. To maximize the return on this
outlay, the system must be utilised as much as possible within
the applicable constraints of security and reliability of supply.
It is expected that power system should operate in a safe
manner at all times. No matter how well designed, faults will
always occur on a power system, and these faults may
represent a risk to personal and/or property [1]. Many power
system experts recognize that it is not feasible to design the
power system to completely prevent the occurrence.
However, it is possible to minimize the damages, using good
design practices and proper relay settings, applying new
protection system technologies, and improving eartihng
system
