Abstract
Induced voltage in a transmission line due to its proximity of another transmission line in the same right of way is often erroneously considered to be solely the result of electromagnetic induction. In general, electromagnetic induction is a function of the loading of the energized line, the proximity of the two lines and the distance that they are paralleled. Most utility personnel are not aware that large voltages can be developed from electric field induction. Unlike electromagnetic induction, electric field induction is a not a function of the distance that the two lines are paralleled. It is primarily a function of the proximity of the two lines and the magnitude of the operating voltage of the energized line. This paper describes a method of calculating the induced voltage caused by electric field induction. Field test results are also shown and potential work hazards are addressed
