A system includes: a sensor configured to detect electrical signals of a cable section for transmitting electrical energy; a processor; a data memory; and a signal interface. The data memory stores a set of curves with an associated distance to the sensor and representing a pulse response of an electrical pulse predetermined by a cable model as a result of a modeled partial discharge at the associate distance. The sensor detects a discharge signal caused by an actual partial discharge on the cable section, and transmits a measurement signal to the processor. Based on the first measurement signal, the processor determines which among the curves in the set correlates best with the first discharge signal, as the first discharge curve. The processor determines a sensor distance between the actual partial discharge and the sensor based on the distance associated with the discharge curve. The signal interface transmits the sensor distance.

System for a cable section, transmission system for transmitting electric energy, and method for operating the system

The present invention relates to an apparatus for calibrating a power measuring system for power transformers. The general inventive concept involves the two reference measuring systems that are known from the prior art for the calibration of a current transformer, a voltage transformer and an evaluation device being integrated in a shared apparatus, according to the invention, for calibrating a power measuring system for power transformers, which apparatus is furthermore arranged on a container such that the apparatus can be moved by means of a trailer that holds the container for the purpose of in-situ calibration of the power measuring system of power transformers.

Apparatus for calibrating a power measuring system for power transformers

The present invention relates to a device for system components of a high-voltage impulse test system, preferably for quality assurance of power transformers. According to the invention, a common base frame having only one main electrode common to the system components is proposed for the spatial collection of the system components.

High-voltage pulse test system

The present invention relates to a controlled truncating radio connection for a high-voltage impulse test system, preferably for quality assurance of power transformers. According to the invention, the truncating radio connection is expanded by an additional damping unit, made of a serial damping resistance and a damping inductance having a radio connection connected in parallel thereto, and thereby combines the functionalities of a truncating radio connection and an overshoot compensation in only one auxiliary component.
