Fig. 311. Thesecondary winding is short-circuited since it consists of a ring ofmolten metal, so that Et, the terminal voltage, is zero, and thesecondary generated voltage E2 is therefore made up of the twocomponents I2R2 and J2X2, where R2 is the resistance of the ringof molten metal and X2 its… … I,R Fig. 311.—Vector diagram for an induction furnace. 295. The Constant-current Transformer.—For the opera-tion of arc lamps in series, the constant-current transformershown in Fig. 312 is used. The primary coil is stationary andreceives power at constant potential, while the secondary coil,which…
