Transient recovery voltage of 400 kV SF6 circuit breaker when clearing short-line fault
Transient recovery voltage (TRV) is calculated according to the IEC standards and using the EMTP- ATP software. Modelling 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.
