Abstract
Abstract:
A method of extracting small amounts of power
directly from the ambient electromagnetic field around a 50kV
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
