Table 2 describes the summary of our case study
which the worst case appeared when there is no arrester
installed,since 35 kA of lightning current level has
already caused the transformer to breakdown.The best
option is to comprise at least one surge arrester in the
system to protect the transformer and for the case when
only SA1 was installed (Case iii),it is the best arrester
placement option in order to ensure the voltage level at
service transformer within the safety margin in the
presence of unpredicted very high transient current level
injection.The voltage has been clamped to safety level
earlier at the substation entrance as to protect the first
equipment that is the capacitive voltage transformer.As
the voltage propagates through the system,it is observed
that the voltage is still within the safety margin although
maximum current is injected to the system.
The modeling concept and parameter selection to
model a substation were presented for the simulations of
substation performance in order to investigate the failure
probability of crucial component in the substation.The
validation of the result was earlier compared with
previous work done by Savic and Stojkovic to make sure
the model was valid.The results showed that the default
arrangement of TNB substation (Case i) was over
protected which the cost of implementation of such
arrangement is high.The placement of arrester is
crucially needed in order to optimize the substation
performance in term of its reliability and cost effective.It
was suggested that the arrester was best suited for
optimized performance if it was installed at the substation
entrance compared to towards the end of substationconnection that was near the service transformer,since
the first arrester could deal with and maintain the voltage
level within safety range even though with a high current
injected.Since the risk of vandalism and mugging
activities of TNB equipment was reported to be really
critical in recent days,therefore,such optimized
substation design is considerably needed in order to have
a more cost effective station as well as reducing the risk
of reckless behavior by irresponsible public and at the
same time maintaining the reliability of the station in the
presence of stresses to the system.
