Multilin Generator Protection

[Power2all]

Setting up 2 MVA, 4160 Genset Protection Relay. I notice input settings for a transformer (Not CPT) and the manual makes reference to transformer differential. What transformer information should be entered... utility by chance?

Which relay? GE make at least three or four generator relays.

G-30 - Looks like they expect a step up/down after generation. I think I should just ignore this setting.

I would suggest carefully reading section 5 of the manual. It deals with GE's concept of sources. If not connected via a Transformer, perhaps consider entering the XFMR as a 1:1 voltage ratio with all windings connected wye (star)-wye (star). If unsure, you really have to test with relay test set to get a feel.
