Oil as an Insulator

[William R. Walsh]

Hi!

Looks like a switch was opened on the 3 phases but the current didnt
want to disconnect. Gotta be in the megavolts?

Thanks! But what were those things that appeared to be "moving back"?
Fusible links?

I had to slow the video down a few times to figure it out myself. At
firsdt it looked like on of the arms was melting, but it's rotating
away from the viewer. There are three sets of switch arms and the
arms rotate open - think drawbridge on its side.


Lousy ascii top view of closed versus open.
