Claim 17:
18. An electronic power meter for monitoring an electrical distribution system providing power to a load, the electronic power meter comprising:
a housing;
at least one sensor disposed in the housing and coupled to the electrical distribution system, 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 disposed in the housing and 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 disposed in the housing and configured to store at least one first firmware, a selection of at least two wiring setup configurations of the electronic power meter and at least one measured and/or calculated parameter of the electrical distribution system, each wiring setup configuration including at least two tests used to verify if the electronic power meter is wired correctly;
at least one processor disposed in the housing that calculates parameters of the electrical distribution system, retrieves the at least two tests from the at least one memory based on the selected wiring setup configuration and determines if the electronic power meter is wired correctly based on executing the retrieved at least two tests using the at least one measured and/or calculated parameters; and
a user interface including a display device disposed in a surface of the housing,
wherein the at least one processor determines the electronic power meter is wired incorrectly if at least one test fails, generates a notification indicating which test has failed to be displayed on the display device and generates at least one second firmware to reprogram the electronic power meter to rectify the determined incorrect wiring based on the failed test, the at least one second firmware reprograms the at least one electronic power meter to perform at least one of the shifting at least one measured current phase by a predetermined amount and/or reassigning measured voltage values from a first voltage phase input to a second voltage phase input, wherein, if the at least one processor determines that the at least one electronic power meter is wired incorrectly, the at least one processor prompts a user via the display device of the user interface to initiate corrective measures; and
if the user activates the corrective measures via the user interface, the at least one processor executes the at least one second firmware.
