| Summary: | This paper presents a numerical modeling and
simulation of 132 kV transmission line in electromagnetic
transient program and later predicts the critical backflashover
current, probability of the transformer damage and
backflashover rate (BFR) when the lightning strikes close to the
substation. The electromagnetic transient program, later
referred as PSCAD/EMTDC is used to model and simulate the
high voltage transmission line. Various parts of transmission
line such as overhead transmission line, tower, footing resistance
and insulators are modeled to study the effect of lightning
overvoltage, at very high frequency, on the BFR when these
parameters are varied. This technique is useful in helping the
utility for conducting an insulation coordination studies as the
outcome can be used in technical evaluation and financial
planning of the transmission systems. |
