Abstract
The circuit breakers had been withdrawn from 345 kV SIC substation. because these were made following the old IEC requirement(IEC 56; TRV rating) and insufficient current rating(2,000 A) for the system requirement(4,000 A). And, they are going to be reused at 345 kV UR substation and SJS switching section. This paper deals with the TRV(temporary recovery voltage) analysis results in order to reuse them. The analysis results are satisfied with the IEC requirements of RRRV(Rate of Rise of Recovery Voltage) and peak voltage(
