I appreciate that everyone has to start learning somewhere and in today's society it seams taboo to deliberately electrocute an elephant, a horse, and lots of dogs "in the name of science" I personally find any kind of animal experiments deplorable and unnecessary.
I am not a transmission man so I found it interesting when in the closing chapter of the book it says that DC is used when transmitting between countries with different frequencies of supply. I could not understand how this could work until.
After a bit of surfing I discovered that it makes sense to convert from one frequency to dc then convert again into the new required frequency. Simple
What I could not find out is why AC cables buried in the ground have a high capacitance effect.
I thought that with the 3 phases close together the magnetic effect would cancel each other out?
It was interesting to find out that HVDC is transmitted in New Zealand
between North and South Island. This system has been operating since 1965
