circuit switcher, circuit breaker

[Mbrooke]

Are circuit switchers employed on the basis which assume bolted faults on the primary are rare? What is the advantage of a circuit switcher over a breaker?

There is also circuit switchers that can add a closing reactor, or resistor for capacitor closing. These would cost less than a syncronous breaker.

It's not transformer protection, but circuit switchers have a place.

Ive seen breaker, reactor then individual circuit switcher to each cap bank. It really seems like breakers do all real fault clearing.
