Abstract

861,276. Electric induction furnaces. ALLMANNA SVENSKA ELEKTRISKA A. B. Dec. 1, 1959 [Dec. 2, 1958), No. 40726/59. Class 39 (3). In an electric vacuum melting furnace having insulated coil turns 1 corona is prevented by surrounding the insulation 2 with spaced conductive layers 3, each of which is connected at 4 to earth or to a potential lying below the critical corona limit. An earthed conductor 4 is also fixed to a conducting layer surrounding the connection lead 5.
