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.

Capacitive power harvesting

Clock reference data may be recovered or updated in networks that include line-powered devices and other devices susceptible to power outages. For example, for a mobile information collection network, one or more devices with extended clock holdover may be strategically deployed throughout the mobile information collection network to provide reference clock data. As another example, battery-powered devices may be woken up in order to provide clock reference data to other devices. Alternatively or additionally, the battery-powered devices may be configured to periodically broadcast their clock reference data to other devices.
