1. In the the design of the relay for autosync of generators, what are the different ways to start the autosynchronizer like autostart command?
2. At what frequency and voltage of generator do we switch to autosynchroniser , is it like around 80% speed and 50% voltage?
3. Do we generally raise the speed to around 80% and then give voltage to field of generator to prevent overexcitation?
4. Do we automatically start autosynchronizer when voltage and frequency reaches certain level without manual command or switch?
5. What is the gain of voltage controller and speed governor in the power plant? I mean gain as if I give 1 second pulse what is the change in voltage/frequency?
