Abstract
A protection system for a power distribution system is provided. The protection system includes a central computer, a plurality of data modules, and a data network. The data modules are each in communication with a different circuit breaker of the power distribution system. The data network communicates between the central computer and the plurality of data modules. The central computer sends an instruction to the plurality of data modules over the data network to aid in synchronization of sampling of a power condition at the plurality of data modules.

14. A method of protecting a power distribution system, comprising:
-
sending a synchronization instruction to a plurality of data modules;
sampling a power condition from the power distribution system in part based upon said synchronization instruction, each of said plurality of data modules being in communication with a different set of separable contacts in the power distribution system;
transmitting a first message containing said power condition from each of said plurality of data modules to a central computer;
determining a second message in said central computer based upon said first message; and
transmitting said second message to each of said plurality of data modules so that one or more of said plurality of data modules operates said different set of separable contacts in response to said second message. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)

22. A power distribution system comprising:
-
a processing unit;
a first power bus for powering a first branch circuit through a first circuit breaker and a second branch circuit through a second circuit breaker;
a first data module configured to operate said first circuit breaker and to sample a first parameter from said first branch circuit;
a second data module configured to operate said second circuit breaker and to sample a second parameter from said second branch circuit; and
a data network linking said first and second data modules to said processing unit, said processing unit performing all primary power distribution functions for the power distribution system based on said first and second parameters, wherein said processing unit communicates a synchronization signal to said first and second data modules so that said first and second data modules sample said first and second parameters, respectively, within a predetermined time-window. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29)
