1. A method for reclassifying measurements made by legacy instrumentation of a power parameter of an electric power line, the method comprising:

  • coupling a sensor to said electric power line;

    monitoring at least one power parameter with said sensor and producing at least one digital representation of said at least one power parameter, said monitoring includes producing at least one of a voltage magnitude, a current magnitude, and at least one of a voltage phase and a current phase relative to a reference, wherein said reference is time derived from a signal received from at least one satellite;

    transmitting a data packet containing at least said digital representation to a microprocessor based device;

    obtaining a measurement of said power parameter produced by said legacy instrumentation;

    comparing said digital representation of said at least one power parameter of said sensor to said measurement of said power parameter produced by said legacy instrumentation to generate compensation data; and

    applying said compensation data to reclassify future measurements of said power parameter made by said legacy instrumentation.
