Abstract: The present disclosure aims to provide a charge unit for a robotic load handling device which reduces the wear/damage experienced by charge contacts of the charge unit and provides a solution whereby easier servicing of the charge unit can be accomplished. A charge unit for a robotic load handling device is operative on top of a grid framework. The charge unit includes a power transfer device is arranged to inductively transfer power to the robotic load handling device, and a supporting structure fixedly attached to a grid framework to position the housing over the grid framework.

Abstract: Disclosed herein are methods, systems, and devices for system event detection associated with power grid components. Methods include detecting, at a plurality of sensors, emissions from a system event associated with at least one winding of a power component. Methods also include determining, using a processor, a plurality of event parameters based, at least in part, on measurements made by the plurality of sensors, the event parameters identifying arrival times of the emissions at each of the plurality of sensors. Methods further include generating, using the processor, an output identifying an estimate of a position of the system event within the power component, the estimate being generated based, at least in part, on the arrival times identified by the plurality of event parameters.
