Yes, - the AVR’s have droop trafo’s installed and they are phased correct (otherwise the reactive loadsharing from remaining part of vessel load would be troublesome too – hope you agree)!!
The connection is made as standard “reactive droop compensation”...
Thanks Mike and Bill, all of the above certainly helps;
however, a few uncertaintie still remain.
I just got this from our expert on the business, who is in on this line of correspondance:

The voltage sensing is correctly a 2-ph sense system – no 3-ph averaging measuring trafo is...
The generators are LETAG 10EXR 315M types, rated at 325 KVA, pf 0.8, originally with SVE S-11P AVRs;
those being ten years old started to break down, and the type was discontinued and we had to find a replacement.
Due to space limitations the Kutai EA08A was selected as being suitable to the...
REf. thread237-286989,
we had to replace the old AVRs on two generators on a marine system incl. frequency converters. The old AVRs are no longer supported, but dod operate flawlessly.
The new AVRs cannot control the voltage on converter operation.
Suppose a low pass filter on th sensing lines...
