Surge Protection w/ Capacitors
Surge Protection w/ Capacitors
(OP)
Why is a capacitor typically placed line-to-ground on each phase conductor as a primary surge protection device?
Thanks,

And, a third way is to think smoothing. That is also what capacitors do. They remove fast changes from the voltage.
All three views are actually one and the same thing and makes use of the fundamental property: i = C*du/dt. The larger the du/dt, the more current through the capacitor.

I forgot the term of transient.
Does everyone agree what they explain above ?

You still need surge arresters to divert the surge to ground, but the duty on the arrester becomes less if surge capacitors are used.

That helps a lot.
