Abstract :
Electrical joints increase their resistance depending on load current and environmental stress. For this reason joints have to be diagnosed in service in order to obtain information about their momentary state. This is mostly done by an infrared snapshot. Based on an analysis of the current method we will demonstrate its shortcomings and an improved new method will be shown.
