Zusammenfassung
This report gives an outline of the investigations on the load of overhead-line-clamps which have been
carried out until now at the Institut fur Elektrische Anlagen und Hoch-spannungstechnik of the Technical
University of Vienna ( * ). The report points out the connection between temperature, wind-velocity, loadcurrent
and bolt-torque of transmission line-clamps. Measuring method was the infrared thermography which
allows the examination of parts of electric high-voltage circuits during operation, without touching them. The
following interpretation of the measurements is given with respect to the influence of heat-reflection. aerodynamics,
choice of reference temperature for computing etc. These influences and the necessary corrections
give the accuracy limit of the applied method.
