Abstract
The interrupting capability of circuit breaker to have an effect on stability and reliability of the power system is largely determined by the fault current and prospective TRV (prospective transient recovery voltage). The prospective TRV, which is essentially a system function determined by the elements of the connected circuit, is not constant for a given system location but is affected by a number of variables. Therefore, the purpose of this study is to analyze the prospective TRV of KEPCO's 345KV transmission system by using EMTP (Electro-Magnetic Transients Program) and to compare the calculated values with the standard values in KSB 150 (1976)
