1. A device for verifying a wire setup of an electronic power meter, the device comprising:
a communication interface that receives a selection of a wiring setup configuration of a plurality of electronic power meters and at least one measured and/or calculated parameter from the plurality of electronic power meters;
at least one memory that stores the selected wiring setup configuration for at least one electronic power meter of the plurality of electronic power meters, the at least one measured and/or calculated parameter received from the at least one electronic power meter, a wiring setup configuration of the at least one electronic power, and at least two tests used to verify if the at least one electronic power meter is wired correctly; and
at least one processor that determines selected wiring setup configuration and retrieves the at least two tests from the at least one memory based on the selected wiring setup configuration and determines if the at least one electronic power meter is wired correctly based on executing the retrieved at least two tests using the at least one measured and/or calculated parameter from the at least one electronic power meter,
wherein the at least one processor determines the at least one electronic power meter is wired incorrectly if at least one test fails, generates a notification indicating which test has failed and generates executable instructions to reprogram the at least one electronic power meter to rectify the determined incorrect wiring based on the failed test and transmits the executable instructions to the at least one electronic power meter via the communication interface, the executable instructions reprogram the at least one electronic power meter to perform at least one of 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 when the wiring setup configuration is a 2 CT delta configuration the retrieved at least two tests include a first test to determine if the measured voltages and currents are above a predetermined threshold, a second test to determine if any voltage phases are swapped, a third test to determine if a Vbc voltage phase is 60 degrees from a Vcb voltage phase, a fourth test to determine if a first current phase is within a predetermined threshold of a voltage Vab phase, a fifth test to determine if a second current phase is within a predetermined threshold of voltage Vcb phase and a sixth test to determine if a current phase is 180 degrees from a predetermined current phase.
