11. An electrical system, comprising:
a conductor bar; and
a neutral and/or ground harmonic filter system comprising a first coil unit and a second coil unit and configured to mitigate neutral and/or ground harmonics of the electrical system, wherein:
the first coil unit comprising a first conductive wire coil, wherein the first conductive wire coil comprises a first end and an opposite second end, the first conductive wire coil is suspended in an insulating material, the first conductive wire coil and the insulating material are disposed in a first non-conductive mechanical structure, and the first end of the first conductive wire coil is electrically coupled to a first contact that extends from the first non-conductive mechanical structure;
the second coil unit comprising a second conductive wire coil, wherein the second conductive wire coil comprises a first end and an opposite second end, the second conductive wire coil is suspended in a ferrous material, wherein the ferrous material comprises metal particles and graphite particles, the second conductive wire coil and the ferrous material are disposed in a second non-conductive mechanical structure, the opposite second end of the second conductive wire coil is electrically coupled to a second contact that extends from the second non-conductive mechanical structure, and the first end of the second conductive wire coil is electrically coupled to the opposite second end of the first conductive wire coil; and
the first contact and the second contact are electrically coupled to a first location and a second location of the conductor bar respectively, wherein the first location and the second location are spaced apart so that a first set of conducting wires of the electrical system are electrically coupled to the conductor bar at locations between the first location and the second location.
