Analysis of Transient Recovery Voltage in 400 kV SF6 Circuit Breaker Due to Transmission Line Faults

Transient recovery voltage (TRV) is calculated according to the IEC standards and using the EMTP- ATP software. Modeling of electric arc for the SF6 circuit breaker is presented. Influence of grading capacitors and line bay disposition on the TRV waveform on the side of the line in a 400 kV substation is analyzed for the short-line fault (SLF) conditions. Fault location at which the rate of rise of recovery voltage (RRRV) is the highest was determined using the EMTP-ATP simulations. Results obtained according to the IEC standards and using the EMTP-ATP are compared.
