I thought direct current had higher transmission losses vs AC
- tallowen 10mo agoAC has higher losses over a transmission wire because of the changing magnetic field that it induces which creates losses.
- HPsquared 10mo agoThere's a cool effect where if you hold a fluorescent tube under a high voltage power line, capacitive coupling from the varying electric field causes it to light up. Some energy is continually leaking out via this route, the tube just reveals it. (Magnetic induction too) https://youtu.be/0D50Dcvzkr4 https://youtu.be/0D50Dcvzkr4

- LargoLasskhyfv 10mo agoNot if it's really high direct current, like https://en.wikipedia.org/wiki/High-voltage_direct_current https://en.wikipedia.org/wiki/High-voltage_direct_current Problem is they need these https://en.wikipedia.org/wiki/HVDC_converter https://en.wikipedia.org/wiki/HVDC_converter , for these https://en.wikipedia.org/wiki/HVDC_converter_station https://en.wikipedia.org/wiki/HVDC_converter_station which are expensive. So it depends on circumstances, how and when its economically feasible to use HVDC, or not.
