    Hello all,

    Is a MOV a form of capacitor or a surge protection device?
    How does it work?

    Thanks folks

    A MOV is a metal oxide varistor. It is used as a surge protector for AC currents, shorting the current when the voltage across exceeds a cetain value.

    Here is a link to the AAC Tutorial on the topic of Non-Linear conduction. The MOV or "varistor" for short exhibits non-linear conductivity.
