Abstract: A plastic robot arm link for a robot includes a body made of plastic material, a connection arranged on the body and adapted to be coupled to a further plastic robot arm link or a transmission part of the robot, and an insertion made of material with a higher strength or stiffness than the plastic material and embedded in the body and/or the connection. By embedding the material with higher strength or stiffness within the body of the robot arm link made of plastic material, the stiffness and strength of the robot arm link can be enhanced. In addition, due to the presence of highly rigid materials, the creep effect of the plastic arm is also significantly reduced, improving the accuracy of the robot.

Abstract: A power distribution equipment personnel safety system includes a vicinity sensor and a power distribution equipment sensor. An outer envelope having a door or cover to an interior of the power distribution equipment is monitored by a vicinity sensor data and a processing unit determines a position of a person in the area outside of the door/cover using vicinity sensor data. When the outer envelope is disturbed where one or more doors or one or more covers are open or not correctly closed or one or more covers are removed, the processing unit determines a personnel safety state and at least one action comprising utilization of the personnel safety state.

Abstract: A method of controlling a mechanical contactor including at least one pair of contacts for conducting a mains current (Im) when the contactor is in a closed position, and an electromagnet arranged to close the contactor, and maintain the contactor in the closed position, by forcing the pair of contacts towards each other when a control current (Ic) runs through a coil of the electromagnet. The method includes, while the contactor is in the closed position, obtaining an indication of unintentional separation of the contacts, and in response to the obtained indication, opening the contactor and maintaining the contactor in an open position by turning off the control current.

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.
