I was amazed to learn that your average synchcheck relay will not detect the wrong phase rotation on one side (say a generator). Even the phase to phase ones! Also as I understand it the SEL300G does not detect this. How can this be! Surely, at commissioning the wrong rotation is a very real possibility. Can anyone explain why there is this the blind spot in design. I would have theought that it is so easy to check on phase to phase units.
