ideality of the circuit breakers
There is one more query about circuit breakers in the master library. I dont find the circuit breakers to be ideal breakers, because when I choose single pole operation of the 3 phase breaker, and enter sufficient delay in opening operation of the 3 poles of the breaker, say 1st pole at 300ms 2nd pole at 350ms and 3rd pole at 400ms, an ideal breaker should open at the predetermined time but it does not happen like that in my case.The instruction says when single pole operation is enabled, the poles of the 3-phase breaker operates independently to each other.
I would like to know if anyone face the same problem with the circuit breakers??
I have attached the snapshots of a 3-phase breaker for determining the transient recovery voltage in the breaker.
This is the output that I get when the single pole operation is enabled and the 3 poles of the breaker is controlled independently for the above mentioned timings.
Can you please help me here, regarding the strange behaviour of the breaker
