Patent ID: 7460347

Claim:
An intelligent electronic device-to-intelligent electronic device direct communication system in a power system, the intelligent electronic device-to-intelligent electronic device direct communication system comprising: a first intelligent electronic device which derives power system data from a selected portion of the power system, the first intelligent electronic device being associated with a first transmit module which transmits the derived power system data; and a second intelligent electronic device which derives power system data from the selected portion of the power system, the second intelligent electronic device being associated with a first receive module, wherein the first receive module of the second intelligent electronic device is coupled to the first transmit module of the first intelligent electronic device via a communication link, such that the first receive module receives the derived power system data transmitted by the first intelligent electronic device, and wherein the second intelligent electronic device provides a redundancy check between the first and second intelligent electronic devices by comparing the power system data derived by the second intelligent electronic device with the power system data transmitted thereto from the first intelligent electronic device.
