ABSTRACT:
A device for immersing and electrically testing an insulating glove in a conductive liquid to determine if the glove is safe for electrical work. The glove is suspended beneath a platform by a pair of insulating barrier rings which clamp the glove cuff therebetween. A hollow electrode extends into the interior of the glove and is connected to a source of water for filling the glove with water. An air sensing tube surrounds the electrode and forms an air passage therebetween and is connected to an air blower and air pressure switch for detecting and deactivating the flow of water into the glove upon it reaching a predetermined level. The inner barrier ring is mounted on a manually movable tube which is telescopically mounted about the air sensing tube and electrode. The platform is movably mounted by an elevator mechanism for immersing the glove in the conductive liquid. The barrier rings reduce the electric field stress and eliminate corona effects on the glove cuff. The glove mounting and filling arrangement eliminates exposed metal parts and reduces accidental flashover by increasing the distance that the electric discharge arc must travel to flashover.
