Thank you for the link to that article.

I am kind of fascinated by such things and after finding out how little I knew about electricity and its application I borrowed a couple of books from my sons education [electrical engineer] and am quite enjoying it.

I appreciate you taking the time.

Brad
interesting link

You are welcome. I teach Electricity/electronics at SCSU, including Transmission systems. Way cool technology. Jim

I'm not Jim, but that's still a fun article to read over, thanks for posting. Of course, its impossible to teach in a few paragraphs what can take years of study and a library full of books to comprehend, but I still enjoy such articles. Much of my electrical engineering design career (retired in 91) was in low voltage (120/240/480) Secondary AC Power Distribution, although I had some experience with our 12470Y 7200 Volt Three Phase Four Wire HV distribution. I left our incoming service (138,000 VAC if I recall) up to the Utility Provider lol.

The interesting thing to me is that the control of DC is now done almost entirely by Solid state electronic power inverters that work in cascaded isolated arrays to allow radical voltage to be manipulated and divided as needed for end use.
The Biggest limitation on the HVDC is the cost of these systems for getting it to Transmission voltage, and then inverting it back down to secondary distribution levels. It seems that the DC line is not friendly to the idea of multiple taps/branching from the HVDC, and is almost always point to point over the entire distance. Jim
