Bus bar design for high-frequency induction heating

WHERE motor-generator sets are used, induction heating coils are frequently located at points remote from the high-frequency generator in a manufacturing plant. In such cases, one or more transmission lines are required. These may be either of the cable or rectangular bus bar type. A subsequent paper will consider the use of cables. The present paper deals with rectangular bus bars. Primary attention is given to the range of frequencies commonly generated by inductor alternators. Current carrying capacity and resistance and reactance per unit length are tabulated for 10,000, 3,000, and 1,000 cycles. Equations are given which apply to much higher and lower frequencies as well. The information supplied has not previously been available to users of induction heating equipment.
