1. A Rogowski coil assembly, comprising:

  • a first Rogowski coil surrounding a conductor and generating a first voltage output signal;

    a second Rogowski coil surrounding the conductor and generating a second voltage output signal; and

    a relay device interfaced with the first and second Rogowski coils and programmed to process the first voltage output signal and the second voltage output signal to calculate a level of noise in the first and second output voltage signals, wherein the relay device is further programmed to process the first output signal and the second voltage output signal to minimize the level of noise in the first and second output voltage signals.
