Abstract

A sensor system for monitoring temperature loads and other impacts on electrical supply installations comprises at least two sensor devices arranged in series at positions in the electrical supply installation to be monitored, one or more signal transmitters connected to each of the sensor devices, one or more signal receivers adapted to communicate with and receive signals from the signal transmitters, and a processing unit connected to at least one of the signal receivers for processing the signals and providing an indication signal.

Claims

at least two sensor devices arranged in series at positions in the electrical supply installation to be monitored;

one or more signal transmitters connected to each of the sensor devices;

one or more signal receivers adapted to communicate with and receive signals from the signal transmitters; and

a processing unit connected to at least one of the signal receivers to process the signals and provide an indication signal.

2. A system according to claim 1, wherein the sensor devices comprise wind strength sensor and temperature sensor.

3. A system according to claim 1, wherein the sensor devices comprise tension sensor and/or height sensor.

4. A system according to claim 1, comprising means for measuring the electrical load at the sensor device(s).

5. A system according to claim 1, comprising means for detecting corona discharges.

6. A system according to claim 1, wherein the signal transmitters and signal receivers are electromagnetic signal transmitters and readers.

7. A system according to claim 1, wherein one or more of the sensor devices are connected to a signal receiver.

8. A system according to claim 1, wherein the sensor devices are electrically connected to the electrical supply installation, the electrical supply installation serving as energy source for the sensor devices.

9. A system according to claim 1, wherein the sensor device has physical contact with the electrical supply installation that is to be monitored.

10. A system according to claim 1, wherein the processing unit is connected to the means for communicating wirelessly with an external unit for transmission of the indication signal or other information related to the indication signal.

11. A system according to claim 8, wherein the external unit is an alarm centre, mobile telephone, computer or the like.

12. A system according to claim 7, wherein the sensor device comprises a transformer for transforming voltage from high voltage to distribution voltage.

15. A method according to claim 1, wherein the sensor devices measure tension and/or height above the ground.

13. A method for monitoring temperature loads and other impacts in electrical supply installations comprising:

placing at least two sensor devices at positions in the electrical supply installation to be monitored;

transmitting sensor signals from the sensor device by means of one or more signal transmitters connected to the sensor devices;

receiving signals from the signal transmitters by means of one or more signal receivers; and

processing the signals and providing an indication signal.

14. A method according to claim 13, wherein the sensor devices measure wind strength and temperature.

16. A method according to claim 13, wherein the signal transmitters and signal receivers are electromagnetic signal transmitters and readers.

17. A method according to claim 13, wherein one or more of the sensor devices receive signals from other sensor devices by means of a signal receiver.
