Abstract
There is disclosed a protection system for a power distribution system having a plurality of breakers arranged in a hierarchy. The protection system has a network and a breaker coupled to the power distribution system. A module is coupled to the network and the breaker is at a first level in the hierarchy. The module samples an electrical condition of the power distribution system at the breaker and monitors the electrical condition for a predetermined trip condition. The module, upon detection of the predetermined trip condition, trips said breaker if the first level is a lowest level of the hierarchy, but monitors the network for a notification message if the first level is not the lowest level of the hierarchy.
