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 is provided of ascertaining an unknown line (conductor) voltage at point X on a power line within an electrical grid comprises collecting raw voltage at or about Point X using a sensor; gathering additional data from data collection sources upstream (comprising, for example a substation) and/or downstream (comprising, for example, smart meters) to Point X (constraining data); using raw voltage, and environment and line data (comprising at least one of GPS location of sensor, GIS data of the electrical grid, phase, type of conductor, total load on conductor), to calculate voltage range at Point X; and using constraining data sequentially to bind (narrow and tighten) the voltage range from a determined range of possibilities to a likely absolute voltage measurement.

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.
