51N Relay Settings for Unigrounded Systems Feeding Delta Connected Loads
51N Relay Settings for Unigrounded Systems Feeding Delta Connected Loads
(OP)
I'm trying to find some further reference material on determining the ground relay settings for a 3 wire solidly grounded system that feeds delta connected loads. (i.e. sub-transmission feeders with Dy1 power transformers) What situations would cause sympathetic trips to occur if the ground settings were set too low other than accuracy of the CT's & relay?
Thanks!
Thanks!
