Hello,

I am simulating a power distribution network, and I am trying to simulate the protection. But I struggle to attach a circuit breakers to the circuit, because they mainly require a digital inputs and from what I understand, they can be used only for electronic purposes. How can include a circuit breaker in my network?

Breaker Block takes a Simulink Signal as input but the signal in the circuit is a Physical Signal. So, it must be converted to a Simulink signal before feeding to Breaker.

Physical signal can be converted to a Simulink signal using PS-Simulink Converter block.

Thank you very much, I would just ask an extra question: Is it possible to make the Circuit breaker not time dependent, since I would love to set it to operate only if certain impedance values are reached, not at some fixed time? Thanks in advance.
