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.

Methods, systems, and devices for accurate signal timing of power component events

A folding shopping cart includes a body frame with a frame connecting base secured at the first end of the body frame. The shopping cart also includes a lower first frame member and an upper second frame member telescopically engaged to define a vertical frame member, wherein a bottom of the lower first frame member is hinged on the frame connecting base. A handlebar is connected with the upper second frame member and front wheels are secured to a second end of the body frame opposite the first end of the body frame. First and second folding rear wheels are respectively secured on opposite sides of the frame connecting base. A button is mechanically linked to a telescopic locking device controlling relative movement between the lower first frame member and the upper second frame member. At least one basket is detachably secured thereto.
