Abstract
There is disclosed a protection system for a power distribution system. The system has a processor, a breaker; a network coupled to the processor, a first module coupled to the network and the breaker, a second module coupled to the network, and an algorithm. The algorithm monitors for a permission to trip request. If a plurality of permission to trip requests are received during a given time period, the algorithm issues a permission granted command to the first module and a hold command to the second module.
