Abstract
A power distribution protection system and method uses communications to coordinate operation of fault protection devices. Communications may be prioritized wherein messages of a lower priority are held or discarded in favor of messages of a higher priority, for example, messages indicating a fault condition. The devices may use multiple channel access schemes in accordance with a priority of a message to be communicated.
