Next part will be uploaded on Wednesday (06.10.2021) at 07:00PM. RE-TRIP is tripping command issued to the same CB (Which doesn't opened from main protection) from LBB/BFR relay. This is issued to ensure that the CB is actually in the stuck condition and there is no issue with the electrical wiring. This command is issued after reset of main protection but before back trip and hence it's time is set as 100ms after receipt of LBB Initiation.
