During the past few decades, maintenance professionals have grown to appreciate the importance of monitoring medium-voltage (4 kV to 28 kV) metal enclosed bus and switchgear. Despite best efforts by the manufacturers in the IR design for indoor and outdoor applications, particularly in industrial environments, the electrical insulation used in switchgear and bus are not immune to aging and degradation mechanisms. The on-line partial discharge techniques developed by Iris Power Engineering for motor and generator monitoring have now been extended to provide cost effective and reliable monitoring systems for metal-clad switchgear and bus.
