摘要： Protection systems for electrical systems such as substation power dividers are described. The protection systems may be designed and used to detect and clear faults that may occur within the substation power dividers. For example, a first Rogowski coil may be used to detect current along a primary conductor, and output a corresponding current signal to a multi-function, differential relay having multiple voltage and current inputs. Similarly, additional Rogowski coils may be used at each of a plurality of secondary feeders, where power from the primary feeder may be distributed to the secondary feeders using a connection bus. By comparing the signals from the first Rogowski coil and the additional Rogowski coils, the differential relay may determine whether a fault exists at some point along the conductor(s) and between the first Rogowski coils and the additional Rogowski coils, including whether a fault is associated with the connection bus. Further, the relay may then, in response to the fault, trip a circuit breaker or other network protection device, so that the fault may be corrected.

摘要： Active crosstalk cancellation in a multi-phase system is achieved using a capacitive voltage divider for each phase in the multi-phase system. A voltage measurement is obtained for the desired phase and each additional phase of the multi-phase system. A product is generated for each additional phase by multiplying each additional phase voltage measurement by a corresponding predetermined constant. The product for each additional phase is subtracted from the voltage measurement of the desired phase.

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.

摘要： A current measurement device using a Rogowski coil having a generally toroidally shaped core with flattened faces, a first winding in one direction, a second winding forming a return loop, and a temperature compensation and scaling network coupled to the coil. The core has concentric cavities and a rough surface to restrain movement of the coil winding A Faraday shield is wrapped over the coil. One shield is “serpentine,” having staggered (offset) lateral extensions from a central region An alternate shield has a generally circular central region with extensions in generally radial directions. The shield is formed of three layers comprising a non-ferromagnetic metal central layer surrounded by insulative layers. At an end tab of the shield, the metal layer is exposed for collection to a ground lug or other connector. An insulative housing envelops the coil and electrical network An output wire terminates in an industrial connector A resistive network may be implemented with the current measurement device. The resistive network may be balanced or unbalanced The resistive network may be capable of signal attenuation of an output, capable of calibration of an output, or provide temperature compensation of an output
