Primary and Secondary Arcs in the Scandinavian Caledonian Chain

Nature, 1963
PROF. J. TUZO WILSON et al.1 have given an outline of the European Caledonian and Hercynian mountains. Regarding the Scandinavian Caledonian chain these authors mention that secondary arcs can readily be made out in Sweden, and that igneous rocks of primary arcs are exposed in the Lofoten Islands off Norway.

Secondary Arc Faults Detection and Determine Arc Extinction Time on Overhead Lines Using Neural Network

Electric Machines & Power Systems, 2000
This paper presents a numerical algorithm for blocking autoreclosure during permanent faults on overhead lines. It is based on one-terminal input data processing. The fault nature (permanent or transient) is determined from the voltage signals of faulted and tripped line phase using neural network approach.
