Revamping of alternator relays with a new relay

Revamping of alternator relays with a new relay

Revamping of alternator relays with a new relay

(OP)
Hi
We have individual relays Microener on our 2 alternators 45 MW 11 kV installed 2006. We have 3 such relays which have failed. These relays are obsolete now. We are planning to do a revamping with a new relay. Can you suggest some make, model which are reliable, can be communicated with online, settings can be changed online, can be ordered directly from the manufacturer? Any other aspects to take into consideration?
