No need to add transformers, the voltage can be set to adjust the voltage to a distant place.
I have adjusted places, sometimes 2 kilometers away, using a secondary carrier back to the generator, or even placing the ELC controller at the load site with a protecting secondary voltage limiter by the generator. There are many ways to do control -- Just do a good analysis and have the necessary equipment.
