it is a very low frequency(50 / 60 Hz). I need a software that can help to simulate all the model of the High voltage transmission line to investigate the electromagnetic filed emission...
Get a free copy of flexPDE from www.pdesolutions.com which will allow you to solve AC Maxwell's equations in two and/or three dimensions. A few such problems are worked in my book entitled "A course in computational electrostatic field theory (CEFT) published by Trafford PuB. You can get a .pdf copy for about $4.00 containing examples and flexPDE programs involving transmission lines.
