适用范围

This standard is revised to change the descriptions of the standard transient recovery voltage (TRV) envelope and ratings. This is applicable for ac high-voltage circuit breakers rated above 1000 V and on a symmetrical current basis. The capability limits of these circuit breakers are determined largely to a major degree by the TRV. The revised descriptions of TRV bring the TRV requirements in IEE...
