    Just make sure it's an insulator, and not an arrestor.
    I took apart a 3kV arrestor a coupla months ago out of 
curiosity. Among the inner workings was a .22 blank. Presumably at a 
certain voltage level the MOV core conducts, and at a certain current 
level the blank fires and blows the thing apart to open the circuit.
    I had previously tried to test the arrestor with an NST (before 
I was aware of its construction), but it didn't fire the blank.
