Abstract
Passive and active methods for anticipating problems with electrical wiring are provided. An insulative material in contact with an electrical conductor has at least one impurity that is impregnated in the insulative material and/or disposed thereon. An environment around the electrical conductor is monitored for the presence or the level of the impurity(ies) emanating from the insulative material in the form of a gaseous effluent. An alarm signal is generated when a predetermined level of the gaseous effluent is detected.
Claims20
A method for anticipating problems with electrical wiring, comprising steps for:
- providing an electrical conductor having an insulative material in contact therewith that (i) provides electrical insulation properties, and (ii) has at least one impurity that is at least one of impregnated in said insulative material and disposed on said insulative material;
- monitoring an environment around said electrical conductor for said at least one impurity emanating from said insulative material in the form of a gaseous effluent;
- and
- generating an alarm signal when a predetermined level of said gaseous effluent is detected.
A method for anticipating problems with electrical wiring, comprising steps for:
- providing a plurality of electrical conductors, each of said plurality of electrical conductors having an insulative material in contact therewith that (i) provides electrical insulation properties, and (ii) has a correspondingly unique impurity that is at least one of impregnated in said insulative material and disposed on said insulative material;
- monitoring an environment around said plurality of electrical conductors for each said unique impurity emanating from each said insulative material in the form of a correspondingly unique gaseous effluent;
- and
- generating an alarm signal when a predetermined level is detected for any said unique gaseous effluent.
A system for anticipating problems with an electrical conductor, the electrical conductor having an insulative material in contact therewith that (i) provides electrical insulation properties, and (ii) has at least one impurity that is at least one of impregnated in said insulative material and disposed on said insulative material, said system comprising:
- means for monitoring an environment around said electrical conductor for said at least one impurity emanating from said insulative material in the form of a gaseous effluent;
- and
- means for generating an alarm signal when a predetermined level of said gaseous effluent is detected.
A system for anticipating problems with a plurality of electrical conductors, each of said plurality of electrical conductors having an insulative material in contact therewith that (i) provides electrical insulation properties, and (ii) has a correspondingly unique impurity that is at least one of impregnated in said insulative material and disposed on said insulative material, said system comprising:
- means for monitoring an environment around said plurality of electrical conductors for each said unique impurity emanating from each said insulative material in the form of a correspondingly unique gaseous effluent;
- and
- means for generating an alarm signal when a predetermined level of any said unique gaseous effluent is detected.
