I have some questions regarding the CT & VT location in the generator terminal box,
1. Droop CT location before the star point at the neutral side of the generator (or) can be at the line side?
2. Why AVR VT sensing has to be taken from the line side and not from the neutral end?
3. What is the purpose of the signal "Generator Current for AVR reference" in the below image as usually only VT sensing is enough for the AVR?
