The invention includes a method, system, and device for communicating a data signal on an electric power system. The inventive method includes communicating the data signal to the electric power system, and modifying the characteristics of the electric power system to reduce the data signal communicated to an electrical component located on the electric power system without substantially reducing a voltage signal. The method further includes communicating the data signal to a customer premise. The electrical component may include, for example, an electrical transformer.

What is claimed is: 1. A method of communicating a data signal on an electric power system, comprising: injecting the data signal on a medium voltage line of the electric power system; bypassing the data signal around a distribution transformer from the medium voltage line onto a low voltage line and transmitting the data signal to a customer premise; and modifying the transmission characteristics of the electric power system to reduce the data signal transmitted to the distribution transformer. 2. The method of claim 1, wherein modifying comprises increasing an impedance imposed by the electrical component on the data signal. 3. The method of claim 2, further comprising increasing inductive properties of the electrical component. 4. The method of claim 3, wherein the inductive properties are increased by an inductor. 5. The method of claim 3, further comprising adding one or more ferrite cores to the electric power system. 6. The method of claim 5, further comprising locating the ferrite cores around a connection point on the electrical component. 7. The method of claim 6, wherein the connection is on a primary side of a transformer. 8. The method of claim 6, wherein the connection point is on a secondary side of a transformer. 9. The method of claim 5, further comprising locating the ferrite cores around at least one conductor attached to the electrical component. 10. The method of claim 1, further comprising increasing an impedance from the electrical component to a point at which the data signal is provided to the network. 11. The method of claim 1, further comprising reducing electromagnetic noise created by the electrical component. 12.
