Abstract: A capacitive voltage sensor arrangement includes a first input terminal, a second input terminal, a first sensor output terminal, and a second sensor output terminal. The sensor arrangement includes a capacitive voltage divider including a primary capacitor arranged between the first input terminal and a first node, and a secondary capacitor arranged between the first node and the second input terminal and electrically connected in series to the primary capacitor. The sensor arrangement further includes a tuning circuit arranged between the first node, a second node, a third node, and a fourth node. The second node is connected with the first sensor output terminal, the third node is connected with the second input terminal, and the fourth node is connected with the second sensor output terminal. The tuning circuit has only one or more passive components.

Abstract: A sensor assembly for a switchgear connector includes a high voltage side facing a switchgear, a low voltage side, and an isolation barrier that provides a galvanic isolation between the high voltage side and the low voltage side. The sensor assembly includes a sensor device measuring at least one physical quantity and outputting a sensor data representative of the at least one physical quantity. The sensor device is arranged on the high voltage side. The sensor assembly includes a data interface arranged on the low voltage side and providing for the sensor data to be accessible from outside of the sensor assembly. The sensor assembly includes a transmission path transferring the sensor data between the sensor device and the data interface. The transmission path has a wireless section extending across the isolation barrier.

Abstract: An outer end cap for sealing a connection end of an electrical connector includes a cover section covering an end face of the connection end and a collar section attached to the connection end. The cover section has a through-hole receiving a sensor cable of a sensor. The cover section and the collar section jointly form a receptacle receiving the connection end. An interior surface of the receptacle has a semi-conductive material. A connector seal is formed on the interior surface of the receptacle and a cable seal is formed in the through-hole.

Abstract: A cable lug for terminating a cable and contacting an appliance includes a cable-side end section directly or indirectly contacting the cable, an appliance-side end section contacting the appliance, and a main body extending between the cable-side end section and the appliance-side end section. The main body has a collar that radially protrudes from the main body.

Abstract: An electrical contact pin for a plug connector includes an outer thread fastening the electrical contact pin to the plug connector and a centering element having a tapered section centering and/or positioning the electrical contact pin. The centering element extends from an end of the electrical contact pin.

Abstract: A method is disclosed for detecting changes in an interval of time (?T) between an optical or electrical signal and an optical or electrical reference signal using a photodetector. The method may be used to synchronize an optical or electrical signal with an optical or electrical reference signal. An apparatus for carrying out the method is also disclosed. The method comprises the steps of: receiving the optical signal and the optical reference signal by means of the photodetector, outputting an electrical response signal at an output of the photodetector, the electrical response signal having a frequency spectrum which depends on the interval of time (?T), filtering a selected harmonic from the frequency spectrum of the electrical response signal which has been output, and detecting changes in the interval of time (?T) from changes in the amplitude of the selected harmonic.
