With an increased emphasis on reducing the size of installations, switchgear designers are faced with the diametrically opposed requirements of increasing short-circuit withstand and continuous current ratings while reducing space for the air that provide both primary insulation and cooling for the energized parts. Using modern material science, compact integrated dielectric systems can be developed...
Recent focus has been placed on improving the reliability and safety of new equipment. This paper describes a few cost-effective upgrades and retrofits for existing electrical systems, which can improve maintenance effectiveness, reduce process downtime, limit physical exposure to hazards, and improve personnel safety. A typical power system, which comprises a high-voltage substation, medium-voltage...
