Calculation of induced EMF by overhead lines

Components of the electric power system influence on its surrounding. The created electromagnetic radiation has an impact on the human body as well as on the electric equipment, such as instrument transformers and power line communication system. A methodology for EMF estimation of neighboring transmission lines was developed. Such parameters as mutual disposition of lines and their wires, the amplitude of the flowing currents and their phase lags were considered. The example of neighboring TLs is examined. Estimation of induced EMF is made. The normal and failure operational modes are considered. Ways for future improvement of the methodology are described.
