Abstract

The present invention relates to a method and an arrangement for visual indication of an electrical quantity, being one or several of power, current and/or voltage through a conductor. The arrangement comprises a substantially wire shaped illuminator and a controller which controls at least one illumination characteristic of said illuminator with respect to said electrical feature.

Claims

1. An arrangement for visual indication of an electrical quantity, being one or several of power, current and/or voltage through a conductor,

wherein the arrangement comprises a substantially wire shaped illuminator and a controller adapted to control at least one illumination characteristic of said illuminator with respect to said electrical feature.

2. The arrangement of claim 1, wherein said wire shaped illuminator is arranged along said conductor.

3. The arrangement of claim 1, wherein said wire shaped illuminator is electroluminescent.

4. The arrangement of claim 1, wherein said wire shaped illuminator is an optical fibre.

5. The arrangement of claim 1, wherein said controller is further adapted to measure said electrical quantity and adopt a control signal to control said illuminator.

6. The arrangement of claim 3, wherein said electroluminescent includes a central conductive wire coated with a phosphorus material coating and transmitter wires wrapped around it, and covered by a coating and a colored vinyl coat.

7. The arrangement of claim 1, wherein said controller comprises a processing arrangement and a measuring arrangement and a driver for driving said illuminator receiving control signals from said processing arrangement.

8. The arrangement according of claim 1, wherein said illumination feature is one or several of intensity, colour or frequency.

9. A cord comprising at least one electric wire and an illuminating arrangement, at least partly arranged along extension of said electric wire, said illuminating arrangement having means for illumination when energized.

10. The cord of claim 9, further comprising a substantially translucent coating, covering said wire and illuminating arrangement.

11. The cord of claim 9, wherein said illuminating arrangement is electroluminescent wire.

12. The cord of claim 9, wherein said illuminating arrangement is an optical fibre.

13. The cord of claim 9, wherein said illuminating arrangement indicates current and/or power consuming through said electric wire.

14. A method of visually indicating an electrical quantity, being one or several of power, current and/or voltage through a conductor, the method comprising the steps of energizing a substantially wire shaped illuminator and controlling at least one illumination characteristic of said illuminator with respect to said electrical feature.
