Hello everyone,
can someone please let me know how to set the settings of a vista protective relay? On what basis is the pick-up, U2 inverse, Instantaneous and the definite time settings selected?

Racobb - I dont have any information regarding the upstream protective device. There is a transformer fuse on the downstream and the transformer itself is rated at 2500kVA at 34500kV/480V,%Z - 5.75.
