Protective Relay Info Needed - IJ7 Differential
Protective Relay Info Needed - IJ7 Differential
(OP)
I'm looking for any available info on some (probably) very old generator diff relays. These are called out as IJ7 (or IJ-7), but no manufacturer is listed.
I'm thinking these are old GE relays. I know GE made an IJD differential relay so these may have been a precursor. They are definitely being used for generator differential.
Based on the age of the facility, these could be quite old (70 years).
Any info would be appreciated.
