Indused longitudinal voltage in parallel overhead transmission lines

Longitudinal voltage, induced by magnetic fields currents in parallel overhead transmission line can effect to linemen that carry out the works in one of this switch off line. Longitudinal voltage values are determined by derivative of Carson integral equations. These equations application is limited by distance between concerned lines that lead to very high miscalculations. Simulator of longitudinal voltage values induced by magnetic field in parallel overhead transmission lines calculation for any distance between lines is suggested.
