Asset management and the role of power quality on electrical treeing in epoxy resin

Abstract

Power network operators in developed countries are faced with the challenge of effectively managing network performance with an ageing asset population. A significant proportion of equipment is already operating well beyond design life, testifying to the success of the many insulation systems employed. Increased production of renewable and distributed energy has resulted in changes of load flows on the network, while demand-side management schemes cause devices results in reduced power quality from disturbances including harmonics. Consequently there is a gradual change in the working environment. Hence at the plant level, insulation systems will age differently influencing electrical ageing mechanisms such as partial discharges and electrical treeing.EThOS - Electronic Theses Online ServiceGBUnited Kingdo
