8. I want to know how they pass a 100 kHz signal thru a 60 Hz transformer
Or even 50 kHz like dial-up internet service, for that matter. The power network is designed for distributing 60 Hz power. If you put a high-speed high-frequency signal on the high voltage (~1000 volt) line, it will be blocked at the first step down transformer, that is basically a low-pass inductive filter.

I suppose they will add capacitors at the transformers to pass the signal around the transformer, but that will mean components, installation, and maintenance costs. Anybody?
