Abstract: 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.
