Closing Resistor Application with Consideration of HV Circuit Breaker Reliability

On the basis of layout of a 420 kV switchgear, Al Anbar, Iraq, six variants of closing a transmission line at no load by a 420 kV SF6 circuit breaker have been selected. For each variant on hundred of examples have been computed, taking into account the asynchronism between the circuit breaker poles (0-5 ms) by the random number method.
