Abstract

The electrical distribution boards and control cubicles, installed inside the ITER tokamak building, can be subjected to a constant or slowly variable magnetic field up to 70 mT, 10 mT/s induced by ITER coils. This is a very unusual environmental condition and there are almost no data available on static magnetic field compatibility for the standard industrial, electrical and electronic components, usually installed inside standard low voltage distribution boards and standard control boards.
A series of tests has therefore been envisaged, in collaboration with EFDA close support unit [I. Benfatto, P. Bettini, M. Cavinato, A. De Lorenzi, J. Hourtoule, E. Serra, Magnetic compatibility of standard components for electrical installations: computation of the background field and consequences on the design of the electrical distribution boards and control boards for the ITER tokamak building, SOFT Conference Presentation, Venice, September 2004] and the Consorzio RFX [L. Grando, A. De Lorenzi, G. Bettanini, D. Desideri, Magnetic compatibility of standard components for electrical installations: tests on low voltage circuit breakers and contactors, SOFT Conference Presentation, Venice, September 2004], to assess the operational limits of these components.
