Abstract: A three-position disconnector switch includes a platform, a power in contact, a power out contact, an earthing contact, and a piston. In a first position, the piston contacts the power out contact and the power in contact. In a second position, the piston contacts the power out contact. In a third position, the piston contacts the power out contact and the earthing contact. The piston moves along an axis to transition between the different switch positions. The power in contact is mounted to the platform, the power out contact is mounted to the platform, and the earthing contact is mounted to the platform.

Abstract: A system for using one of two independent alternating power sources to power a load is provided. The system sets a flux match to a first value, wherein the flux match indicates a set range for switching between powering the load using a first power source and powering the load using a second power source. The system switches between powering the load using the first power source and powering the load using the second power source using the first flux match value. The system further obtains a first set of inrush current values associated with the switching. Based on the first set of inrush current values and a maximum inrush current threshold, the system adjusts the flux match to a second value and switches between powering the load using the first power source and powering the load using the second power source using the second flux match value.

Abstract: The invention relates to a wear ring (10) for mounting on a pipe, tube, cable or the like, more particularly on a corrugated pipe (14). The wear ring (10) comprises two ring halves (18a, 18b), which can be interconnected to form a ring (18), wherein a fastening structure (26), by structures of which the ring (18) can be fixed on the corrugated pipe (14), is provided on the ring halves (18a, 18b). The ring halves (18a, 18b) comprise connecting elements (22), by structures of which the ring halves can be interlockingly interconnected in an axial direction, and the fastening structure (26) is formed by at least one ring insert (26), which can be radially moved on the ring (18) and which can be locked on the ring (18) in a radially inner position in order to fix the ring (18) on the corrugated pipe (14).

Abstract: A method and system for monitoring condition of a fleet of circuit breakers includes: measuring at least one type of operating condition related signal for the respective circuit breakers during their operation; obtaining a set of feature data representing the respective measurements of operating condition related signal; performing cluster analysis of the set of feature data based on a similarity threshold; and generating a signal indicating the condition of the fleet of circuit breakers based on the resulting cluster number. Rather than comparing the data representing the measurements of operating condition related signal to a reference model built on CB's normal data, the method includes applying cluster analysis of the set of feature data representing the respective measurements of operating condition related signal. The method does not need a reference “normal” database for comparison.

Abstract: A power converter includes a power conversion circuit having a first terminal set and a second terminal set, configured to convert power input via one of the first terminal set and the second terminal set and output the converted power via the other of the first terminal set and the second terminal set; a measurement unit; a controller configured to control the power conversion circuit to generate a voltage/current waveform travelling along the first network with a power supplied by a second power source linked to the second terminal set of the power conversion circuit in response to a condition that a change rate of the measurement of the voltage/current exceeds a threshold; and locate a fault on the first network. The power conversion circuit can be re-used for different modes of operation either for power transmission under normal condition or for fault location under fault condition.

Abstract: A method of controlling a visual operator interface having a plurality of predefined areas, which include one or more monitoring areas configured to display visual elements representing a current state of a technical system. According to the method, it is determined that one of the monitoring areas is to be prioritized; and an incomplete visibility decrease in at least one other area of the visual operator interface is initiated, wherein the prioritized monitoring area is unaffected by the visibility decrease.

Abstract: A method of operating a switching device in a system. The method includes monitoring a voltage; operating the system at each of a plurality of system configurations; and, for each of the system configurations and a predetermined same opening angle relative to a reference angle of the monitored voltage, determining a suitable closing angle relative to the reference angle and storing information about the determined suitable closing angle in association with the system configuration in a database. The method then includes, determining a system configuration in the system; at the predetermined same opening angle, opening the switching device; from the database, obtaining a closing angle of the determined suitable closing angles, wherein the system configuration with which the obtained closing angle is associated in the database corresponds to the determined system configuration; and at the obtained closing angle, closing the switching device.
