- TL;DR Summary
- Why can displacement current travel through dielectric medium in capacitors but has no effect between interrupted contacts.
I’m self taught so I have a lot of holes in my understanding. I also have little to no mathematical understanding. Even though ironically, I tend to prefer to picture electricity as numbers rather than “water” in a pipe, etc.
I’ve been studying displacement current recently and have a question.
Displacement current can exist in a vacuum, and the contact gap in a MV/ HV vacuum interrupter is relatively small. Why do you not see current flow through the circuit with contacts open?
My theories are that;
1) if Displacement current = conduction current, you need a closed circuit conducting current to obtain displacement current. No conduction, no displacement.
2) the gap on a vacuum interrupter is too far apart
Help understanding this would be much appreciated.
