Is it malfunctioning of MATLAB Simulink Three-phase Circuit Breaker block?

12 December 2018 0 8K Report

I have simulated two three phase systems employing Three-phase Circuit Breaker Block in MATLAB Simulink. In both systems when there is fault, circuit breaker is opened. But the interruption of all the three phases is not at same point. There is Time lag as shown in figure. Is it Normal? What could be the reason?
