We have new relays (multifunction relay, bur from other company), finished design and build cubicle.
I calculated all setting again, but before commissioning, I would like check myself again. For this propose I need tech documentation of GE.
Thanks

RE: GE generator protective relay
Great! I would trust the new calculated settings rather than matching or even comparing with the existing.
What's the benefit of comparing to old settings? Who is to say that the old settings were properly calculated. In fact, there may be a chance of misinterpreting the old settings.
RE: GE generator protective relay
You are right.
But my problem is not setting, my problem is customer.
Before two years, I'm provide (sorry for I am, I mean our team)retrofit for two generators for same customer, same history, customer requested compare new setting to old.
I check, change, but in dynamic and on load test puted our new setting. Different between these cases:
Now it is generator GE and protection is GE, we retrofit GE relays to relays from other company.
In previos case we retrofit old protection relay to new from same company.
And you also right in other.
In both of case, old setting is not so correct.
I think is also intresting thread: retrofit of old protection
