Hi,a vendor has offered me 2 similar distance relays for 230 kv transmission line protection.usually we reqiure 2 different hardwares or 2 different algorithms in relays for distance protection.but this vendor has no such thing.I want to know your experience and ideas about using similar distance relays for high voltage transmission lines .any comments would be appreciated.
thanx
