As I understand it a MOV (Metal Oxide Varistor) is basically a whomping
Zeneer Diode in essance. It does nothing untill you reach a prescribed
voltage, then acts as a short circuit. A hogh voltage gate essentially. Am I
Assumeing I am right (hey, this is my dream remember?) then how is this
different than a spark gap?
Do they reset after use? or simply short out and need to be replaced.
If these behaive like a gap, then why use them in place of a gap in an NST
protection circuit? pros/cons?
