Abstract: An energy harvesting device (CTH) installed in an electrical distribution system (EDS) for powering ancillary electrical devices (AD) used in the distribution system. The device includes a first voltage regulator circuit (CC) configured to produce a voltage matched to a power curve of a current transformer (CT) to which the device is electrically coupled. The device also includes a second and separate voltage regulator circuit (SVR) which continuously operates to maximize the amount of electrical energy recovered from the current transformer.

Abstract: Improved power line management is provided by the systems and methods disclosed herein that accurately measures voltage in a power distribution system. In various embodiments, the system may include one or more sensor units, each coupled to the power lines using a capacitive or resistive voltage divider to yield a voltage at a sensor unit that is within a measurable range. In one aspect, this voltage may also be used to power the sensor unit and/or other devices coupled to it.
