I want to model the residual voltage for capacitor switching. Can you help me?

To model the initial conditions (voltage) of a capacitor bank, you should use a "parameter event" (SetParam) on the variables "uC_a", "uC_b", "uC_c" (signals of the "ElmShnt"). Please find attached an…

How can I model the arc voltage characteristic of a circuit breaker?

The arc voltage of the circuit-breaker can be modelled as a nonlinear resistance. Therefore we connect a resistor (series impedance)in series with the circuit-breaker. Both the real and imaginary part…
