the basis of using differential relay instead of distance relay in short transmission lines
the basis of using differential relay instead of distance relay in short transmission lines
(OP)
Hi everybody
I would be thankful if anyone explain me about the scientific or standard reference about using of differential relay instead of distance relay in short lines.some specialists believe that SIR>>>5 (approximately 10) is the basis of selecting 87 instead of 21.I would be grateful that someone explain me that if there is any standard,reliable reference or even an essay about this.
best regards

Why make some kind of rule like the SIR?
So what text book did the SIR>>>5 come from?
