    摘要: In a method for determining the electrical loadability of power lines by temperature measurement, the temperature is measured with at least one sensor arranged on the power line and connected to a data processing system, wherein the time-dependent temperature of the power line is determined by an existing or a weighted load parameter, and wherein based on the electrical current and the temperature measured by the sensor, taking into account either the existing or a weighted load parameter, a time-dependent electrical load is determined in the data processing system.

    摘要: A device for determining partial discharge in an insulation system of a rotating electrical machine with low capacitance decoupling has a coupler as a high pass and an adapter device connected or connectable to the coupler. The adapter device has a frequency separating filter for dividing a decoupled signal provided by the coupler into a high frequency signal and a low frequency signal. A mixer is provided for the high frequency signal and the low frequency signal for converting the high frequency signal. An output is provided where the converted high frequency signal is tapped for evaluation by an evaluation device connectable to the adapter device.
