Please explain the functionality of generator breaker automatic re-closure logic in MKV GE Frames gas turbines logics. What is the significance of signal L2G? My understanding is GE allows automatic re-closure of generator breaker within 30 seconds after breaker opens up first time following a Start. Is this true? In my opinion the breaker should not be allowed to re-close automatically and operator has to intervene for safer operation. However, if the breaker opens up from some part load then operator has to interven and press the START button in order to re-close the breaker but during first time breaker closure following unit start, this is not the case and the logic tries to re-close the breaker automatically until timer 30 seconds get lapsed thereby unlatching 1X. Please put some light on this logic and process.
