Abstract: A tool and method for handling a part within an electrical power transmission system is disclosed, the part having a flange with a hole through the flange. A first jaw and a second jaw are connected to pivot relative to one another and have respective ends that converge upon closure, for example to hold the flange between the respective ends. The first jaw may have a tooth extended at the respective end of the first jaw for fitting within the hole in the flange to hold the flange between the respective ends when the tool is in a closed position. The tool may be a hot stick adapter, or may include a hot stick made at least in part of dielectric material. An actuator may be connected to operate one or both of the first jaw and the second jaw from a user end of the hot stick.

Abstract: An applicator tool is disclosed for applying a fastener between cooperating surfaces of a dielectric protector placed at least partially over a component of an electrical power transmission system, the applicator tool made at least in part of dielectric material and comprising: a structural frame element; a fastener mount connected to the structural frame element and moveable relative to the structural frame element between a first position and a second position to at least partially define a fastener drive path; and an actuator connected to drive the fastener mount from the first position to the second position to apply in use a fastener, mounted on the fastener mount, through cooperating surfaces positioned on the fastener drive path. A tool is also disclosed for holding together in alignment two mating surfaces with pre-drilled holes and applying a fastener to penetrate the holes and secure the mating surfaces together.

Abstract: An apparatus and method are used for remotely blocking a cavity of a component_of an energized electrical transmission system. A protector has a blocking part for blocking the cavity of the component. The protector has a hotstick connector. A dielectric hotstick has an engagement part such as a hook at a remote end of the dielectric hotstick. The hook may be removably connected to the external point of attachment for remote installation of the blocking part blocking the cavity within a component, such as a piece of equipment or support structure. The blocking part may be remotely installed blocking the cavity using a dielectric hotstick operated by a user who is in a position outside a safe Limit of Approach. The blocking part may comprise a compressible material such as rubber or memory foam.

Abstract: A protector for a boom tip for use within an electrical power transmission system, the protector including: one or more walls having a boom tip enclosure side, an exterior side, and one or more terminal edges that define a boom tip entrance; and a guide shoulder contoured along the boom tip enclosure side to define an installation path for a part of the boom tip to contact and follow relative to the protector. A method of installing a protector on a boom tip for use within an electrical power transmission system, the method including: positioning the protector so that the boom tip is between one or more terminal edges of the protector, and a part of the boom tip is adjacent an initial portion of a guide shoulder contoured along a boom tip enclosure side of the protector; and advancing the protector into an installed position over the boom tip by allowing the part to follow an installation path defined by the guide shoulder.

Abstract: An apparatus and method are disclosed for protecting a component of an electrical power transmission system. The apparatus comprises: a dielectric cover having opposed portions that define a component enclosing space when in a closed position; the dielectric cover having an open position in which enclosing edges of the opposed portions are spaced to allow entry of the component between the enclosing edges into the dielectric cover; and a spreader, connected to the opposed portions for moving the opposed portions into the closed position, and having a tool connector for operation of the spreader by a tool. The spreader may be configured to exert positive control in use to hold the opposed portions in position over a range of positions between the closed position and an open position.
