摘要： 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.

摘要： In a method for monitoring an electrical energy transmission device, time-resolved operating state data, environmental state data, and/or sensor sensor data are recorded. The operating state data relate to current, past and/or future operating states of the electrical energy transmission device; the environmental state data relate to current, past, and/or future states in an environment of the electrical energy transmission device; the sensor data are detected by at least one sensor of the electrical energy transmission device. The operating state data, the environmental data, and/or the sensor data are processed with a computational model to calculate a temperature curve of current, past and/or future temperatures of at least one module of the electrical energy transmission device. Based on the calculated temperature curve, a thermal load capacity of the module is determined based on a thermal load threshold for the module.

摘要： A monitoring method for an electrical energy transfer device which has a first phase conductor and a second phase conductor, includes the following steps: a temperature of the first phase conductor is compared with the temperature of the second phase conductor and a signaling is performed if there is a deviation between the temperatures. The electrical energy transfer device is, for this purpose, equipped at the first phase conductor with a first temperature sensor and at the second phase conductor with a second temperature sensor.

摘要： An electrical power transmission device includes at least one switching unit having at least one contact fitting for electrically contacting the switching unit. Furthermore, the switching unit has a sensor for monitoring the state of the switching unit. The sensor is supported by the contact fitting. The sensor is at least partially masked by the contact fitting.

摘要： In a method for determining a fluid density of a fluid in an encapsulated electrical device a sensor unit is used to acquire measurement data. The fluid density is derived from the measurement values. Weather data relating to weather conditions in an environment of the electrical device are collected. Via machine learning, a digital model is generated for the influence of the weather conditions on a measurement deviation of a measurement value from the true fluid density. Using the digital model, a correction value is calculated for measurement values according to the weather data and a measurement value is corrected using the correction value.

摘要： 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.
