Patent number: 11476705Abstract: A power harvesting device is provided that may supply low voltage power to operate devices in remote locations. The power harvesting device may be connected to a medium to high voltage power line. First and second capacitors divide the voltage to a lower voltage sufficient to power a device, such as a monitoring device. The power harvesting device and monitoring device may be connected to an electric tower with the power harvesting device being connected to a power line supported by the tower.Type: GrantFiled: December 13, 2019Date of Patent: October 18, 2022Assignee: ABB SCHWEIZ AGInventors: Nirmal Paudel, Vivek Siddharth, David Raschka, Ronald D.
