Abstract
A method of extracting small amounts of power directly from the ambient electromagnetic field around a 50 kV AC single phase line is described using a new approach to coupling capacitance. The amount of the power that may be extracted is limited. The proposed solution is vastly more cost effective than the alternatives of a transformer or a directly connected capacitive tap. The modelling and design limitations of the method are described and demonstrated on a scaled model.
