Abstract

In this letter, we show that contrary to common belief, counter-transposing the conductors when power cables are cross-bonded can increase the positive-sequence resistance by close to 20%. This is very important because the losses of a power cable are determined (for balanced operation) from the Joule loasses caused by the positive-sequence resistance (3R1I 12).
