چکیده
|
Lightning is the main factor of outage and insulation breakdown of power system. the lightning event can produce dangerous overvoltage, equipment failures, and power supply interruption. in this paper, externally gapped line arresters (eglas) performances have been investigated to evaluate the lightning performances of a typical 63 kv transmission line. a probabilistic analysis has been done to study the egla performance in transmission line by monte-carlo method. the results show the egla performance dependency to soil resistivity and lightning strike parameters.
