Abstract: A three-position disconnector switch includes an earthing contact, a power out contact, a power in contact, a piston, and a threaded rod. A length of the piston is such that in a first switch position an outer surface of a wall of the piston makes an electrical contact between the power out contact and the power in contact. The length of the piston is such that in a second switch position the outer surface of the wall of the piston does not make an electrical contact with either the earthing contact or the power in contact. The length of the piston is such that in a third switch position the outer surface of wall of the piston makes an electrical contact between the earthing contact and the power out contact. The piston includes an inner threaded section configured to engage with the threaded rod.

Abstract: A method is disclosed for inspecting electrical components within a housing. The method may be useful for identifying dust, grime, corrosion, tree-like structures, edges and/or slots on electrical components. The method includes capturing two optical images of an electrical component and comparing the images. Variations in pixels between the two images may be used to generate warnings.

Abstract: A switch includes a power in contact, a piston, a power out contact, a plurality of flexible locking elements, an earthing contact, and a threaded rod. In a first position, the piston contacts the power in contact and the power out contact. In a second position, the piston contacts the power out contact. In a third position, the piston contacts the earthing contact and the power out contact. The piston comprises an inner threaded section that engages the threaded rod. Rotation of the threaded rod moves the piston along an axis of the switch between the different switch positions. The piston comprises a groove extending in a direction parallel to the axis. Each of the flexible locking elements is configured such that a part of each of the flexible locking elements moves into and out of the groove as the piston is moved along the axis of the switch.

Abstract: A power distribution equipment personnel safety system includes a vicinity sensor and a power distribution equipment sensor. An outer envelope having a door or cover to an interior of the power distribution equipment is monitored by a vicinity sensor data and a processing unit determines a position of a person in the area outside of the door/cover using vicinity sensor data. When the outer envelope is disturbed where one or more doors or one or more covers are open or not correctly closed or one or more covers are removed, the processing unit determines a personnel safety state and at least one action comprising utilization of the personnel safety state.
