Abstract
The sheath proximity loss of single-conductor cables is calculated by Miller´s equation [1]. However, this equation involves a correction term which causes considerable error in calculated values for large-size, aluminum-sheathed cables. Taking the self-inductance of eddy current into account, the author has derived the exact equation. Miller´s equation is no longer valid, especially for large-size, aluminum-sheathed cables.
