I was trying to simulate single phase transient analysis across a CB (single frrquency transient), to match that Transient Recovery Voltage reaches 2Vmax. But i found it to be different when I set my parameters. Max voltage for L=6 and C=1e-6 goes beyond 2Vmax. I have attached my slx file also. I am just unable to figure out what I am doing wrong???

The transients that occur during switching are due to residual energy stored in capacitance (C), inductance (L), or both. This energy is released when the circuit transitions from one steady state to another as a result of an interruption.
For a precise understanding of TRV in a specific application, it is essential to refer to standards such as IEEE C37.011 or IEC 62271-100, which provide guidelines on TRV requirements for different types of circuit breakers and system conditions.
