ABSTRACT:
A capacitor for use in a medium voltage capacitive voltage divider according to the present invention includes spaced plates encapsulated within an insulating material, the resulting device being usable as a supporting insulator as well as a voltage divider. The plates are configured such that there are no sharp corners or protuberances exposed therebetween, thus minimizing arcing propensity. The capacitor includes a first disc-shaped plate supported by a coaxial rod connected to a corresponding terminal. Dielectric material is cast around the first plate and a second plate is disposed over the exterior surface of the cast dielectric material. An exterior insulating material is encapsulated around the second plate which is electrically connected to a second terminal.
