HVDC Circuit Breaker: Is This _Really_ Difficult?

[Bret Cahill]

All this should have been well settled before Tesla was born.

It seems a HVAC circuit breaker would be more difficult.

DC is much harder to switch.

So the big "climate science" genius hasn't a clue about electricity. Very
"green" of you Bret. Try going with actual facts rather than your
liberal "emotions" of what "seems" difficult.

Here. wait. Let me demonstrate what a dummy you are. AC current is
constantly reversing. So that means the current is actually shutting off
120 times a second (for 60 hz) power). So is that why an AC switch is
"more difficult"? Get a science education Bret, and THEN come back and
start telling us about "climate change".

Now you are on to something.

Climate Change is caused by air conditioners, not man.

HVAC usuallt means something else,

DC is harder to switch than AC. judging only from the rating seen on
datasheets and parts at low voltages it seems to ba about 8 times harder.


I don't see why this switch is needed though, to stop the current just
turn off the inverter or the generator field..
