Abstract

An electromagnetic radiation detecting system within an electric system, the electromagnetic radiation detecting system comprising: a plurality of induction rings, each for surrounding one of a plurality of electric lines of the electric system; and a controller connected to the plurality of induction rings, for measuring voltages produced by the plurality of induction rings, and for indicating, from the measuring, electric lines corresponding to induction rings having non-zero sum total electric current flows, thereby indicating the electric lines as being electromagnetic radiation pollution sources.

Claims

1. An electromagnetic radiation detecting system within an electric system, said electromagnetic radiation detecting system comprising:

at least two induction rings, each for surrounding one of a plurality of electric lines of said electric system, wherein each of said surrounded electric lines comprises one or more wires; and

a controller connected to said at least two induction rings, for concurrently measuring voltages produced by said at least two induction rings,

for indicating, from said measured voltages, the correct wiring of said one or more of said plurality of electric lines corresponding to said at least two induction rings producing said measured voltages, dependent on a sum of total electric current flows,

wherein when said one or more of said plurality of electric lines indicates a zero sum total electric current flow, said zero indication relates to correctly connected wiring thereof,

and wherein when said one or more of said plurality of electric lines indicates a non-zero sum total electric current flow, said non-zero indication relates to a single wiring failure of at least two non-correctly connected electric lines,

said non-zero indication thereby accomplishing tracing of electromagnetic radiation pollution sources in the electric system, by associating said single wiring failure with said at least two induction rings.

2. An electromagnetic radiation detecting system according to claim 1, further comprising:

a map comprising physical locations of said plurality of electric lines of said electric system within a structure,

thereby indicating physical locations of said one or more of said plurality of electric lines being the electromagnetic radiation pollution sources.

3. An electromagnetic radiation detecting system according to claim 1, further comprising:

a conversion table, for determining a radiated distance for each of said plurality of induction rings having non-zero sum total electric current flows, as a function thereof,

thereby indicating physical distances from said one or more of said plurality of electric lines as being electromagnetic radiated.

4. An electromagnetic radiation detecting system according to claim 1, wherein each of said plurality of electric lines being surrounded comprises an electric line selected from a group consisting of:

a ground line;

a one-phase electric line, consisting of a live wire and of a neutral wire;

a three-phase electric line, consisting of a first phase wire, of a second phase wire, of a third phase wire, and of a return wire of said first, second and third phase wires,

thereby for correct wiring of the electric system, all of said plurality of induction rings produce zero voltages.

5. A method for detecting electromagnetic radiation within an electric system, said method comprising the steps of:

surrounding at least two of a plurality of electric lines of said electric system, each by an induction ring, wherein each of said surrounded electric lines comprises one or more wires;

concurrently measuring voltages produced by at least two of said induction rings;

indicating, from said measured voltages, the correct wiring of one or more of said plurality of electric lines corresponding to said at least two induction rings producing said measured voltages, dependent on a sum total of electric current flows,

wherein when said one or more of said plurality of electric lines indicates a zero sum total electric current flow, said zero indication relates to correctly connected wiring thereof,

and wherein when said one or more of said plurality of electric lines indicates a non-zero sum total electric current flow, said non-zero indication relates to a single wiring failure of at least two non-correctly connected electric lines,

said non-zero indication thereby accomplishing tracing of electromagnetic radiation pollution sources in the electric system, by associating said single wiring failure with said at least two induction rings.

6. A method according to claim 5, further comprising the step of:

mapping physical locations of said plurality of electric lines of said electric system within a structure; and

indicating physical locations of said one or more of said plurality of electric lines being the electromagnetic radiation pollution sources.

7. A method according to claim 5, further comprising the step of:

converting each of said non-zero measured voltages, produced by said plurality of induction rings, to a distance,

thereby indicating physical distances from said one or more of said plurality of electric lines as being electromagnetic radiated.
