If I am not mistaken we already use HVDC on high power runs due to its much lower loss ? How does this beaker change that ?

- surbas 14y agoAccording to the article HVDC is only used for point to point electrical runs, because managing grids of it is very hard. What the breaker does is allow for easier managing of the grids by allowing parts under going surge, like from a lighting strike, to be segmented off.
- crusso 14y agoExactly. The modern AC power grid is very resilient due in part to the multi-interconnect nature which allows for parts of the grid to go down without taking down the whole network. On an AC grid, there are breakers that automatically disconnect and often reconnect. http://en.wikipedia.org/wiki/Recloser http://en.wikipedia.org/wiki/Recloser I guess that this HDVC hybrid breaker accomplishes more or less the same thing.
- kens 14y agoA friend's father worked on a massive DC power line project in Manitoba in the 1960s [1], so HVDC technology has been around for a long time. The article discusses a potential incremental improvement that might make HVDC useful in more circumstances, but the article seems to be making HVDC sound like a big new breakthrough.
