Abstract
A method is provided for marking electrical wiring with condition indicators. One or more markers are added to one or both of the insulative material and a surface of an electrical conductor such that it bonds thereto. Each marker is capable of emanating into a surrounding atmospheric environment as a gaseous effluent in response to a specific condition experienced by the electrical conductor.
Claims18
A method of marking electrical wiring with condition indicators, comprising steps for:
- providing an electrical conductor having an insulative material in contact therewith that provides electrical insulation properties;
- and
- adding at least one marker to at least one of said insulative material and a surface of said electrical conductor, each said marker being molecularly bonded to said at least one of said insulative material and said surface of said electrical conductor, each said marker emanating into a surrounding atmospheric environment as a gaseous effluent in response to a specific condition experienced by said electrical conductor.
A method of marking electrical wiring with condition indicators, comprising steps for:
- providing an electrical conductor having an insulative material in contact therewith that provides electrical insulation properties;
- and
- adding a plurality of markers to at least one of said insulative material and a surface of said electrical conductor, each of said plurality of markers being molecularly bonded to said at least one of said insulative material and a surface of said electrical conductor, each of said plurality of markers emanating as a unique gaseous effluent into a surrounding atmospheric environment in response to one of a plurality of specific conditions experienced by said electrical conductor.
A method for anticipating problems with electrical wiring, comprising steps for:
- providing an electrical conductor having an insulative material in contact therewith that provides electrical insulation properties;
- adding at least one marker to at least one of said insulative material and a surface of said electrical conductor, each said marker emanating into a surrounding atmospheric environment as a gaseous effluent in response to a specific condition experienced by said electrical conductor;
- monitoring said atmospheric environment for said 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 provides electrical insulation properties;
- adding at least one unique marker to at least one of (i) said insulative material for each of said plurality of electrical conductors and (ii) a surface of each of said plurality of electrical conductors, each said unique marker emanating into a surrounding atmospheric environment as a gaseous effluent in response to a specific condition experienced by said electrical conductor;
- monitoring said atmospheric environment for said gaseous effluent of each said unique marker;
- and
- generating an alarm signal when a predetermined level of said gaseous effluent of any said unique marker is detected.
