Abstract: A method based on the telegraph equation to simulate the vacuum power flow in magnetically insulated transmission line was introduced. Shot 4600 at Angara-5-1 facility was computed, and the simulation results agree well with the experiment results. The loss current of the elements at joints of different MITL structures was analyzed. Also, the difference between this method and other circuit simulation methods such as TLCODE and Bertha was discussed. The method is a new way of estimating the vacuum power flow in magnetically insulated transmission line. It can not only enhance numerical convergence of solution, but also ensure the numerical precision and self-consistency in loss current calculation. -
