    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.

    Abstract: A system for monitoring a switchgear includes an infrared camera; a processing unit; and an output unit. The infrared camera acquires a first infrared image having a first number of pixels, and the processing unit determines a pixel in the first infrared image with a maximum temperature. The processing unit utilizes a second number less than the first number to determine a temperature interval for the first infrared image equal to a difference between the maximum temperature in the first infrared image and a threshold temperature in the first infrared image. The processing unit is configured to determine that a hot spot exists in the switchgear using the temperature interval for the first infrared image.

    Abstract: A switchgear or control gear includes: a first compartment; at least one removable module; a plurality of main switchgear or control gear components; and a plurality of auxiliary switchgear or control gear components. The plurality of main switchgear or control gear components are sub-divided into a first group of components that have a lifetime greater than a threshold level and a second group of components that have a lifetime less than or equal to the threshold level. The plurality of auxiliary switchgear or control gear components are sub-divided into a first group of components that have a lifetime greater than the threshold level and a second group of components that have a lifetime less than or equal to the threshold level.

    Abstract: A medium voltage switchgear or control gear includes at least one first compartment; a cable compartment; a plurality of main components; and a plurality of auxiliary components. The plurality of main components is housed in at least one part of the at least one first compartment. The plurality of auxiliary components is housed in the cable compartment. The second connector is configured to connect to the first connector to connect a cable in the cable compartment to a component of the plurality of main components. The cable compartment is configured to be disconnected from the at least one first compartment and wherein the cable compartment is configured to be spatially separated from the at least one first compartment.

    Abstract: A three-position disconnector switch includes an earthing contact, a power out contact, a power in contact, and a piston. The power out contact comprises first and second parts connected by a leg portion. In a first position, the piston contacts the first part of the power out contact. In a second position, the piston contacts the first part of the power out contact and makes electrical contact with the second part. In a third position, the piston contacts the second part and makes electrical contact with the earthing contact. The piston is configured to move along an axis of the three-position disconnector switch to transition the three-position disconnector switch between the different switch positions.
