- TL;DR Summary
- This generator G1 is connected to an AVR, what I don't understand is why the excitation is separately by voltage G3 and current G2.
Any explications please
Thanks
I need help with this Generator excitation method please

In summary, the conversation discusses a three-phase AC alternator, which is regulated by the current in coils and the rotating dipole field. The unit also has a current transformer for sensing and a current limiter or protection circuit. The purpose of G2 is unknown and the make and model of the unit is also unknown. It is questioned whether the unit has slip rings or is brushless and transformer coupled like a marine unit.

Welcome to PF.
This appears to be a three-phase AC alternator, not exactly a generator.
T32 may be the slip ring terminals, not a regulator. The current in those coils regulates the field, and so the voltage generated. G3 provides the rotating dipole field.
At the bottom, P1-P2 is a current transformer sensing the AC current from V2. That is the sensing part of a current limiter or protection circuit.
Just what G2 is for, I yet know not.
What is the make and model of the unit?
Does it have slip rings, or is it brushless, transformer coupled, like a marine unit?
