(a) When computations are performed to determine the electric and magnetic fields, the following input data shall be used:
1. The highest operating voltage and the MCR (computations shall consider phase angles and normal current flow directions).
2. The minimum conductor clearance to the earth.
3. Voltages and currents shall be assumed to be balanced in phase and in magnitude.
(b) The computations shall be conducted with a computer program easily available to and acceptable to the Department.
(c) The computations shall be conducted for the new or modified electric power transmission line or subtransmission line only, without consideration of other existing electric power lines or other sources of 60 Hz magnetic fields.
