Abstract:
This invention relates to a method and apparatus for executing secondary functions on an electrical switchgear device. In particular, the present invention relates to a method and apparatus which is implemented in the processing electronics of an electrical switchgear device which has a primary trip or protection function and also the capability to execute secondary functions or applications, such as over/undervoltage conditions and near fault warning levels and display. These secondary functions or applications being user configurable and are subject to processing availability and the constraints of the primary protection function.
