Monitoring system and device for an electric power line network
First Claim
1. A device for monitoring an electric overhead line, the device being an independently operating real time multisensor for mounting in a position on a line span, with a built-in transmitter for transmitting sensor signals to a remote central, from built-in sensors for sensing at least one parameter in a parameter group that comprises angle of inclination, line sag increase, wind speed, wind direction, quality/stability of line current, line temperature and air temperature, characterized in that the multisensor further comprises a camera for real time image monitoring of the line and its surroundings, the camera further being operative to present at least one of said parameters visually as a part of the camera image, the camera image being transmitted as a sensor signal in real time to the central.

Abstract
A device is provided for monitoring an electric overhead line, which device is constituted by an independently operating real time multisensor for mounting in a position on a span of the overhead line. The device has a built-in transmitter for transmitting sensor signals to a remote central, and comprises a laser range finder for measuring distance to the ground beneath the overhead line, as well as a camera for visual inspection of the line and its surroundings.
