Abstract :
An accurate new model for calculating AC resistance of ACSR conductors has been developed and verified for single, two and three layer conductor designs. Current redistribution was found to be far more important in determining the AC/DC resistance ratio than hysteresis losses in the steel core except in single layer conductors. The model suggests ways of reducing the AC resistance and promises to be a useful design tool.
