How can I compute induced currents on shield wires?
Although the programs currently do not have the ability of calculating induced currents on shield wires (this feature is coming), you can use ENVIRO to help out with this task. Do the following: • If your model consists of a simple transmission line right of way you can compute the induced currents in the shield wires using ENVIRO. • Take the induced currents computed by ENVIRO and type them into the load configurations for the towers. • Calculate the final magnetic fields. • You must rerun the induced current calculations in ENVIRO for each loading condition that you wish to model.
