    Abstract: The present disclosure relates to a method for controlling personal protective equipment. The method comprises positioning of a person (120) equipped with, personal protective equipment (122) next to an electrical enclosure (110), wherein a specific personal protective equipment requirement (112) is defined for the electrical enclosure. The method further comprises scanning the personal protective equipment in a contact-less manner while the person is next to the electrical enclosure. Thereby scanned personal protective equipment information (132) are generated. The method further comprises comparing the scanned personal protective equipment information with the specific personal protective equipment requirement and evaluating, based on the comparison, whether the personal protective equipment is in accordance with the specific personal protective equipment requirement. The method further comprises providing a feedback indicating whether or not the personal protective equipment is in accordance with the specific personal protective equipment requirement.

    Abstract: The present invention relates to a composite insulator (1) and a method for producing the same. The composite insulator (1) comprises an insulating elongated core (2), a protective layer (3) surrounding the elongated core (2), the protective layer (3) comprising an outer surface (4) with a shed profile and an adhesive primer layer (5) disposed between the elongated core (2) and the protective layer (3) for adhering the protective layer (3) to the elongated core (2), the adhesive primer layer (5) comprising a coupling agent (6) and particles (7) of a low resistivity material. The method for producing a composite insulator (1) comprises preparing a first solution comprising a solvent, a coupling agent (6) and particles (7) of a low resistivity material, applying the first solution on at least a part of an envelope surface of an insulating elongated core (2) and thus forming one or more first adhesive primer layers (5) and applying a protective layer (3) onto the first adhesive primer layer (5) on the elongated core (2), wherein the protective layer (3) comprises an outer surface (4) with a shed profile.

    Abstract: The present disclosure relates to a filled silicone rubber (SiR) material (2) comprising at least 20 wt% of alumina tri-hydrate (ATH) as a filler (4) dispersed in SiR (5) to below the percolation threshold. The ATH is a mixture of a first ATH powder and a second ATH powder. The particle size distribution of the first and second ATH powders are such that the d90 value of the second ATH powder is less than the di0 value of the first ATH powder. The disclosure also relates to an insulator 1 made from the filled SiR material (2), and to a use of the insulator in a high-voltage direct current (HVDC) application.

    Abstract: A bushing for high voltage applications comprises a conductor surrounded by at least one foil (22) of conductive material, where the foil has an edge over which a layer (26) of semiconductive paint stretches. The semiconductive paint comprises flakes of thermally reduced graphene oxide as a field grading material having a conductivity that varies with electrical field strength. The layer (26) has a thickness and the flakes have at least one width, where the thickness is smaller than the width.
