Tap-off power from a transmission line shield wires to feed small loads

摘要

In this article, the feasibility to obtain power from the shield wires of a transmission line, as a result of the electromagnetic induction effect, will be presented. The phase conductors of the considered transmission line are horizontally arranged each having a quadruple bundle configuration. The transmission line used during the study operates at 525 kV. The results obtained showed that this form of power generation can be a feasible and cost-effective alternative for feeding small loads along a transmission line when compared to other forms of electricity supply. In order to obtain the highest induced current some shield conductor configurations were analyzed. The simulation tool used for analyzing the electromagnetic induction was the Alternative Transients Program (ATP).
