Re: [TCML] MOTs
Ive seen the inside of pole pigs with aluminum primary windings, its
more like a wide flat strap instead of wire.
As to solid-state pigs... well how do you think they do big HVDC power
conversion? Giant solid state inverters is how... Of course its
still at power frequency (50/60hz) so the transformers arent "solid
state" like the HF NSTs out there. You could make pole pigs a tiny
fraction of their existing size if we could convert to a 40khz grid or
something ;-). Corona problems would be greatly exacerbated at
hundreds of kV... it would be quite a show!
