Abstract

A method ascertains the risk of condensation in an enclosure of a high-voltage device. The interior temperature in the enclosure is ascertained using an interior temperature sensor arranged in the enclosure, thereby obtaining interior temperature values TI. An exterior temperature of the enclosure is ascertained using an exterior temperature sensor arranged outside of the enclosure, thereby obtaining exterior temperature values TA. The interior temperature values TI and the exterior temperature TA values are transmitted to a data processing unit. The data processing unit ascertains a temperature difference value TD by calculating the difference between the interior temperature value TI and the exterior temperature values TA based on TD=TI−TA. The data processing unit generates a warning signal if the temperature difference value TD lies below 3° C.
