1. An intelligent electronic device (IED) comprising:

  • at least one sensor coupled to an electrical distribution system providing power to at least one load external to the IED, the at least one sensor configured to measure at least one parameter of the electrical distribution system and generate at least one analog signal indicative of the at least one parameter;

    at least one analog-to-digital converter configured to receive the at least one analog signal and convert the at least one analog signal to at least one digital signal;

    at least one memory configured to store at least a first firmware and a second firmware, the second firmware being a previously stored version of the first firmware; and

    at least one processor configured to receive the at least one digital signal and calculate at least one power parameter of the electrical distribution system, the at least one processor further configured to determine if there is an error associated with the first firmware, wherein if the at least one processor determines there is no error associated with the first firmware, the at least one processor is configured to execute the first firmware and if the at least one processor determines there is an error with the first firmware, the at least one processor is configured to execute the previously stored second firmware.
