INTERNAL BEHAVIOUR OF LARGE COILS SUBJECT TO TRANSIENT VOLTAGE

INTERNAL BEHAVIOUR OF LARGE COILS SUBJECT TO TRANSIENT VOLTAGE This paper deals with the problem of internal overvoltages within large coils due to fastrising surges. Numerical simulations are performed on a lumpedparameter equivalent circuit, representing a coil of the magnetic system of a thermonuclear fusion experiment. Inductances and capacitances are computed through numerical methods which ensure a good precision even with complex geometries. The effect of the conductive painting on the outer surface of the coil is also taken into account. The simulation results are compared with a number of measurements on a fullsize prototype coil. Turntoearth, as well as interturn overvoltages, are both computed and measured in many grounding conditions. The experimental results fit well with computation and theoretical prediction. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png COMPEL: The International Journal for Computation and Mathematics in Electrical and Electronic Engineering Emerald Publishing

Abstract

This paper deals with the problem of internal overvoltages within large coils due to fastrising surges. Numerical simulations are performed on a lumpedparameter equivalent circuit, representing a coil of the magnetic system of a thermonuclear fusion experiment. Inductances and capacitances are computed through numerical methods which ensure a good precision even with complex geometries. The effect of the conductive painting on the outer surface of the coil is also taken into account. The simulation results are compared with a number of measurements on a fullsize prototype coil. Turntoearth, as well as interturn overvoltages, are both computed and measured in many grounding conditions. The experimental results fit well with computation and theoretical prediction.
