Hi bro very nice video , I have one doubt . For distance protection we will take tie CT also, if you take tie CT that portion also gets covered thn y need of teed protection
Tie CT is between 2 feeders. And Tie CB is closed always , so for fault in any one of feeder 1 or 2 Tie CT will sense fault current, so you can not distinguish in which feeder actual fault occurred.
Fantastic
Very good. Thanks 🙏🙏🙏🙏🙏🙏
How is T Differetial protection of 1.5 CB scheme differs from the Stub Protection? Do we really need 3rd line CT of one bay for Tee Diff protection??
Ct1 is responsible for line protection .Ct5 is responsible for busbar in my site scheme
Depends on site requirement and design.
@@eddycurrent1187 thanks for your response.can u explain application wise both of methods.
