Verification of the transmission line circuits by using time delay
Information
In this model, the verification of the TransmissionLineModelica and the TransmissionLineEquations are performed.The formula of the time delay is used for the verification of the implemented transmission line circuit models to check whether the time delay of the models satisfies the theoretical one. Time delay between the ends of a transmission line can be calculated as follows:
The parameters for the TransmissionLineCheck are:
