I am working in a thermal (coal) power plant. and so I have some question about my desicion. firstly I want to know that if a unit trip from
the boiler protection or turbin protection; the breaker of field open immediately or 10 or 12 second later. main stop valves were closed
immediately or a little open began the trip for the security of balance the rotor a little second open. so our system desicion unit triped
after 12 second later circuit breaker open. is it normal or abnormal. thank you
