Category: Issue for edition 2 of this part


In a recently commissioned project it was noticed that breaker command execution for 220 kv switchyard in a 7SJ64(FBCU) relay is executed throught the relay IEC tag which uses the same take to make the command high after synch check.Is it a correct way of implementation ?


Discussion Created Status
It is not clear, what is meant with 'command is executed through the relay IEC tag'. If you mean that the command has to use the 'synchrocheck override' tag to close a breaker, which has no synchrocheck configured, then this implementation is wrong. 06 Mar 09 Not Applicable
