Recloser Vs Circuit Breaker
Recloser Vs Circuit Breaker
(OP)
Hello everyone,
I have a very very basic question, but it seems that I can't find an answer that satisfies my curiosity
What is the difference between a Circuit breaker and a Recloser?
Thanks in advance for the help

"a breaker can be used as a recloser in conjunction with relaying,but has to be derated "
can you explain me a little more about this. We have a client that want to add reclosing on his circuit breaker, what do we have to derate and how much? The interrupting rating?
Also i know that we have to look if the charging time of the closing coil is less than the reclosing delay. You cannot close before the breaker is charge.

tem1234, i am not sure for the derating question in my experience that comes from oil breakers, but has no effect in the gas cb. a gas cb is designed to withstand the rated interruption. most cb's either have logic built in (most commonly an Agastat time delay) in the closing circuit, or have a delay in the relaying - this is not required for the first operation.
the timing that i am aware of for a spring mech cb as a recloser can have an immediate O-C, and O- then a short time delay - required to charge after opening again ~13seconds, and then the final time will stay open to be reset manually.
if there is a hydraulic mech it can go for 6, sometimes 7, operations before being recharged.
this is a scheme that i am familiar with. would like to hear of others.
