Hi
Can any one help me to find the relation between the withstand short circuit current and the number operations relation for vacuum and SF6 medium voltage circuit breakers.
For example if I have circuit breaker with 31.5 kA at the manufacturing date (No. of operations = zero), what will be the withstand short circuit current after 2000 operations.
Thanks
