Abstract: A method and an apparatus for training a model for predicting a temperature rise of a heating element in a switchgear. The method includes obtaining a model for predicting the temperature rise. The method also includes obtaining n+1 sets of physical quantities in relation to the heating element, each set of physical quantities being collected at a corresponding one of n+1 time points spaced apart from each other by a time step in a normal operation state of the heating element, each set of physical quantities comprising a current and an actual temperature of the heating element and an ambient temperature. The method includes converting the actual temperature in each set of physical quantities into an actual temperature rise based on the corresponding ambient temperature; and training the model with the current, the actual temperature rise and the ambient temperature to determine the several parameters.

Abstract: An apparatus for a drive for driving an externally excited synchronous motor. The apparatus includes means for performing the following. The apparatus causes the drive to operate in a primary operating mode for achieving unity power factor. The apparatus monitors stator flux linkage load angle, stator flux linkage and torque references. In response to the stator flux linkage load angle reference, in a steady state, reaching or exceeding a pre-defined maximum allowed stator flux linkage load angle for steady state operation, the apparatus causes the drive to operate in a stator flux assistance operating mode. In the stator flux assistance operating mode, an increased stator flux linkage for allowing operation with the pre-defined maximum allowed stator flux linkage load angle with unity or maximized sub-unity power factor is used as the stator flux linkage reference.

Abstract: An apparatus and a method for handling twistlocks configured to lock a container onto a vehicle. The apparatus includes a gripper configured to grip one of the twistlocks to be mounted onto or dismounted from a corner fitting of a container. Further, the apparatus has a visual sensor configured to capture a first image of the corner fitting when the vehicle is moving in a twistlock handling station. The apparatus includes a control unit configured to obtain, from the visual sensor, the first image; make some determinations based on the first image; and send a handling position such that the gripper moves to the handling position to handle the one of the twistlocks during the moving of the vehicle.

Abstract: The present disclosure relates to a grinding sander. The grinding sander includes a sanding plate configured to move in an operation state, and a plurality of limiting members disposed on a surface of the sanding plate to define a plurality of strip-shaped slot areas. Each strip-shaped slot area is configured to allow at least one strip-shaped sandpaper to be correspondingly mounted therein to effect sanding of a surface of an article via the strip-shaped sandpaper under the movement of the sanding plate. The grinding sander of the present disclosure may be used to perform high-quality sanding of a narrow surface of an article.

Abstract: A method and an apparatus for use in an earth-fault protection in a three-phase electric network, the apparatus configured to detect a phase-to-earth fault in the three-phase electric network, to determine for each of the three phases of the three-phase electric network a phase current during the detected phase-to-earth fault or a change in the phase current due to the detected phase-to-earth fault, to determine an estimate of an earth-fault current on the basis of the determined phase currents or on the basis of the determined changes in the phase currents, to determine, if the estimate of the earth-fault current represents an actual earth-fault current or an apparent earth-fault current, and to determine, in response to determining that the estimate of the earth-fault current represents the actual earth-fault current, that the estimate of the earth-fault current is valid.

Abstract: An arc mitigation apparatus for an air insulated switchgear includes: a flap; a switch; and a control mechanism. The flap is installable in a wall of a compartment of a medium voltage switchgear. When the flap is installed in the wall of the compartment of the medium voltage switchgear, the flap permits when open air and/or gas passes through the flap from inside the compartment to outside the compartment. When the flap is installed in the wall of the compartment of the medium voltage switchgear, the flap is movable from a closed position to an open position due to a pressure difference between an inside of the compartment and an outside of the compartment. The switch activates based on movement of the flap. The control mechanism sets a flap threshold pressure for the flap with respect to the pressure difference that will move the flap.

Abstract: A technique for a control method and a control system in a substation is provided. The control system includes a substation feeder, an intelligent electronic device, IED, a merging unit, and BUS network connecting the IED and the merging unit. The control method includes providing measurement signals by the substation feeder to the merging unit, transmitting, by the merging unit, measurement data based on the measurement signals of the substation feeder to the IED via the BUS network, identifying, by the IED, a fault condition based on the measurement data, transmitting, by the IED, a conditional control command to the merging unit via the BUS network, determining, by the merging unit, whether the condition of the conditional control command is met, and if so initiating, by the merging unit, the control measure of the substation feeder circuit.

Abstract: An electric machine including a stator and a frame, the stator is supported with support necks on the frame in at least two axially spaced support locations. The support locations include a first group of support necks and a second group of support necks. The support necks in the first group are positioned in connection with a vertical centre plane. The second group includes two side support necks positioned opposite to each other at an angular distance above or below a horizontal centre plane. The angular distance is defined by a first angle which is determined in degrees by the formula α1=(90/P)±(⅕)*(90/P), where P is the number of poles of the electric machine and P>2.
