摘要： Methods and system for making and using vacuum switching devices are disclosed. A vacuum switching device has an operating rod for actuating a movable electrical contact within the device. The operating rod may be a hollow epoxy glass tube with an electrical sensor disposed within it, and there may be an elastomeric polymer filling compound disposed within the tube and encasing the sensor. The operating rod may be attached to the movable electrical contact on one end by a steel end-fitting that has been press-fit into the tube and secured with at least one cross pin. In this way, a very secure electromechanical connection may be made between the operating rod and the rest of the vacuum switching device, and the sensor is protected from shock associated with the operation of the device. Moreover, the vacuum switching device is compact and easy to construct.

摘要： A current measurement device using a Rogowski coil having a generally toroidal-shaped core with a first winding in one direction and a second winding forming a return loop. The coil is positioned within a two-piece electrostatic shield. A first piece of the electrostatic shield is a partially donut-shaped member having a U-shaped cross-section. The coil is positioned in the donut-shaped member and covered by an encapsulating material. The first piece includes a slit through the cross-section thereof to prevent an electrical loop around the perimeter thereof. The second piece of the electrostatic shield is flat and has a donut-shaped configuration. The second piece is configured with inside and outside peripheral edges such that only one or none of the inside/outside edges contact the first piece. The second piece also has a cross-sectional slit which is in registry with the slit in the first piece.

摘要： A precision printed circuit board based Rogowski coil is formed including a printed circuit board including a first layer and second layer. The printed circuit board further defines an aperture for receiving an electrical path therethough. A first return path is defined about the aperture on the first layer of the printed circuit board, and a second return path—parallel to the first return path—is defined about the aperture on the second layer of the printed circuit board. A plurality of radial paths defined on the first layer of printed circuit board extend between the aperture and the first return path. A plurality of radial paths defined on the second layer of the printed circuit board extend between the aperture and the second return path. Each first layer radial path is connected with an adjacent second layer radial path to form a generally toroidally-shaped winding.

摘要： An method for automatically testing an arc flash detection system by periodically or continually transmitting electro-optical (EO) radiation through one or more transmission cables electro-optically coupled to respective EO radiation collectors. A test EO signal may pass through the EO radiation collector to be received by an EO sensor. An attenuation of the EO signal may be determined by comparing the intensity of the transmitted EO signal to an intensity of the received EO signal. A self-test failure may be detected if the attenuation exceeds a threshold. EO signals may be transmitted according to a particular pattern (e.g., a coded signal) to allow an arc flash detection system to distinguish the test EO radiation from EO radiation indicative of an arc flash event.

摘要： An improved Rogowski coil is formed on a toroidal core made of a thermoplastic or other moldable material, the core having a preferably continuous groove or grooves extending around the core. The grooves correspond in size to magnet wire which registers within the grooves, thus controlling the specific location of the wires. The grooving may be helical. A return loop can be provided for return path cancellation, or a reverse winding can be added in a direction opposite to the direction of advancement of the main coil. In using the return loop, a resistive network can be added to improve the cancellation of the return path due to the effect of geometries. In addition, it can compensate for thermal and other variations.
