I need help with this Generator excitation method please

AI Thread Summary
The discussion focuses on a three-phase AC alternator, clarifying that T32 likely refers to slip ring terminals rather than a regulator. The current in the coils is responsible for regulating the field and the generated voltage, while G3 contributes to the rotating dipole field. P1-P2 functions as a current transformer that senses AC current from V2, indicating its role in a current limiter or protection circuit. There is uncertainty regarding the purpose of G2, and additional information is sought about the make and model of the unit, including whether it has slip rings or is brushless. Understanding these components is crucial for effective excitation method implementation.

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

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?
 

Thread 'How might electronics be different if AC voltage was 72V at 45 Hz?'

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?

Thread 'What happens if shielded cable has a short to the shield?'

While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...

Thread 'Why does the amperage go real high if there is a low voltage short?'

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
