Hi, I am an automation expert and we have a turbine siemens the question is when we want to do a test turbine overspeed it triggers a default of over-frequency programmed in siprotec 4 .the tie circuit breaker is open and the voltage regulator remains in mode on

Ok, then turn off the AVR either from HMI or locally, before doing the overspeed test.

If you turn off the Voltage regulator - no generator voltage - no overfrequency
