Suppression of signal transmission over a conductor

An apparatus for suppressing transmission of signals over a conductor coupled between a power source and a signal source powered thereby, the system comprising:

• a first input for receiving power from the power source via one or more power conductors;
• a second input for connecting to a ground conductor;
• an output for providing the received power to the signal source and coupling the signal source with the ground conductor;
• and
• a circuit coupled with the input and the output, the circuit comprising:
• means for altering the shape of a fundamental current and voltage waveforms and altering and diminishing any non-fundamental frequency waveforms such that they are not measurable or detectable;
• and
• means for preventing the communication thereof via inductive coupling of any electrical signals on mains current onto the grounding path or vice versa;
• and
• wherein the electrical signals impart one or more characteristics on the ground conductor, and further wherein the means for preventing further includes a secondary winding operative to sense the one or more characteristics one the ground conductor, the secondary winding being coupled with a processor operative to convert the sensed one or more characteristics to digital data representative thereof and process the digital data to derive at least one result therefrom.

A method of suppressing transmission of signals over a conductor coupled between a power source and a signal source powered thereby, the method comprising:

• implementing, electrically, a circuit between the power source and the signal source receiving power therefrom, the circuit receiving power from the power source and conveying the received power to the signal source, the implementing further comprising:
• coupling a first inductor in series between a first conductor and a first output line, wherein power supplied by the power source to the first output line flows through the first inductor;
• coupling a second inductor in series between a second conductor and a second output line, wherein power supplied by the power source to the second output line flows through the second inductor;
• coupling a third inductor connected in series between a ground conductor and a third output line, wherein ground conducted from the signal source to the third output line flows through the third inductor;
• and
• wherein an inductance of each of the first, second and/or third inductors increases when power at frequencies greater than the nominal frequency flows through the first, second or third conductors respectively;
• and
• wherein the signals from the signal source impart one or more characteristics on at least the third conductor, the method further comprising:
• providing one or more of the first, second or third inductors with a secondary winding operative to sense the one or more characteristics in the first, second or third conductors respectively, each of the secondary windings being coupled with a processor;
• and
• converting, by the processor, the sensed one or more characteristics to digital data representative thereof and processing the digital data to derive at least one result therefrom.
