Sir, what is under operating of relay? As seen by the circle plot, the relay should operate as soon as the fault value enters the circle i.e. after point B. But the relay takes time upto point C to operate due to arc resistance. Is this the actual meaning of under operation of relay?
Sir Due to Arc Resistance , the slope of line will also change as Total resistance increase...will it change or not?? If it changes our RX diagram will also change...
At point c impedence seen by relay is less than relay set , so relay operate why you called it as Mal operation occurring chance there sir ? and how can the locus of power swing can be drawn that passing through electrical centre.
sir can you please elaborate because in hunting synchronous motor will search for synchronisam and in power swing rotor angle is searching for new stable system.@@lecturesinelectricaleng
