If current of a motor(group) starts exceed the other's group current, the differential relays react to it, decreasing generator's exaltation, so controller setting stays unchanged, but the output power of generator became reduced, fuel feed reduced, wheelslip reduced, so when current become equal again, the exaltation will be restored, fuel flow increased to compensate increased load of diesel.

Hey Weter, you keep using the word "exaltation". This is a different word from "excitation". Just in case some are wondering what you mean by that word.

Magnetizing of generator's loop, causing the current to be initiated.
Ouch, I have learned just a little wrong word.

This is the 1970's wheelslip control in the US.

Indeed Mike. I have sometimes been excited but sadly I don't think I've ever been exalted... :)

Right on, but you must have been in a "state of extreme happiness" at least once in your life, as I have been. Hahaha,

Mismatch between wishes and abilities, though.
