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.

High-voltage device and method for ascertaining the risk of condensation in cabinets in a high-voltage device of this kind

A method for monitoring an operating state of an energy supply network connects a data processing cloud to selected communication units at a query time over long-range communication connections. Selected communication units transmit measured values and/or values derived therefrom to the data processing cloud over a long-range connection. To receive measured values and/or values derived therefrom, each communication unit is connected, over a short-range communication connection, to at least one sensor on or in a high-voltage device of the network for capturing measured values. The data processing cloud determines the network operating state within an analysis based on measured values and/or values derived therefrom. To provide a simple and cost-effective analysis of the entire network operating state, the data processing cloud during analysis uses measured values and/or values derived therefrom from at least two selected communication units at different locations.
