Abstract: A heatless slurry system for use with a glass removal apparatus for restoring a glass surface. The system comprises a slurry container and a pump mounted externally relative to the container to prevent heating of the slurry as the system is operated. Vacuum pressure is created by activation of the pump to promote circulation of the slurry within the tool, thereby allowing the latter to be worked against the surface.

Abstract: A device and method for reducing the risk of a streamer initiated flashover across a high voltage insulator under normal operating voltages. The device includes a support structure adapted to be grounded and mounted in proximity to the high voltage insulator; and space charge producing conductors wound around the support structure and forming coils for producing space charge in a proximity of an insulator to be protected, and inhibiting a formation of positive streamers, each conductor having a diameter not exceeding 0.1 mm for reducing a corona inception voltage of the support structure upon which each conductor is wound, in both dry and wet conditions.
