Abstract: A combined energy harvesting and measuring device, for use in harvesting energy from a power line conductor and in optimizing load balance and charge as between one or more energy storage or energy drawing devices comprises a single, multi-function current transformer (CT) which itself comprises an electrical winding disposed thereon, the CT being configured to receive an induced current on the electrical winding via magnetic flux energy generated by alternating current on the power line conductor and, at the same time, being configured to measure current flow on the power line conductor; and wherein there is a circuit electrically coupled to the electrical winding and configured to convert the harvested and received induced current into an electrical energy for consumption by an electrical device.

Abstract: A method of correcting the non-linearity of a sensor on a linear, high voltage power line comprises removably fixing a sensor on a conductor carrying an AC signal amplifying the current signal and calculating and calibrating a desired gain such that a non-linear signal from the sensor is converted to a linear signal.
