Patent ID: 8493231

Claim:
A power meter having fault tolerance, comprising: a housing; a first power monitoring device that performs a power management function and calculates first power management data, the first power monitoring device positioned within the housing; a second power monitoring device that performs the power management function and calculates second power management data, the second power monitoring device positioned within the housing; a controller in communication with the first power monitoring device through a first communication path, and with the second power monitoring device through a second communication path, where the first communication path and the second communication path do not share a common communication path; and a network connection in communication with the controller, where the controller is configured to receive the first power management data and the second power management data, and to selectively couple the first communication path or the second communication path to the network connection based on a corruption analysis of the first power management data and the second power management data and where the first power monitoring device and the second power monitoring device are configured to generate energy consumption data when the other of the first power monitoring device and the second power monitoring device is serviced.
