Abstract

Device for the survey of temperature variations in a direct current electrical installation, comprising a first temperature sensor (2) for the survey of the temperature of an electric circuit, a first displaying device (5) for displaying the surveyed temperature value, a second temperature sensor (3) thermally connected to the first temperature sensor (2), and a switching device (7) connected to the second temperature sensor, apt to activate an alarm system (10,12) when the temperature of the circuit reaches a predetermined alarm threshlod.
