Under reaching Zone 1 of Distance relays
Under reaching Zone 1 of Distance relays
(OP)
Generally speaking the zone 1 of distance relays is intentionally set to under reach the line length to the tune of 70 to 90 %. Also we know that the under reaching zone 1 is likely to over reach in case the parallel line is out of service and earthed. I invite reders your comments on ways to over come this quandary.

I have read some technical documents that reference the paper, I have been looking for it on the Net with no luck at all, up to date.
