A New Transmission Line Representation of Eddy-Current Problems in Cylinders

A new method of approximating a distributed wedgeshaped transmission line by a lumped line is presented. This line is easier to build because all the capacitors have the same value. This approximation should be useful when the simulation of time varying fields is required for studying Eddy-current problems in non-linear magnetic cylinders. Comparisons made between the exact solution, the classical lumped line and this new approach show that this new approach is more accurate for a given number of sections.
