Protection systems for electrical systems are described, where the electrica l systems may include spot networks and/or grid networks. The various protecti on systems may be designed and used to detect and clear faults that may occur within the electrical systems. For example, a pair of Rogowski coils may be used to detect current along a conductors at their respective locations on t he conductors, and to output corresponding signals to a multi-function, differential relay having multiple voltage and current inputs. By comparing the signals from the Rogowski coils, the differential relay may determine whether a fault exists at some point along the conductors and between the pa ir of Rogowski coils. Further, the relay may then, in response to the fault, tr ip a circuit breaker or other network protection device to address the fault.</ SDOAB>
