GEC CDG 34 Electromechanical Relay
GEC CDG 34 Electromechanical Relay
(OP)
Hi
I have a one off GEC CDG 34 relay to test, a legacy relay left on a fairly new system, it protects an 11kV transformer feeder. The remainder of the relays are modern digital type.
Can anyone suggest a suitable secondary test set for the high currents involevd?

Thank you for the advice. Scotty, there is a CDG14 protecting the same feeder for earth fault, so the CDG34 is probably only doing overcurrent. I've confirmed it's a 5A relay, so a fairly high burden. The sverker unit we have will probably be ok, it can deliver up to 50 single phase with the elements linked out.
Thanks all.
