Title: Eddy Current versus Joule Heating Effects for a Cable Suspended in an Iron Pipe
Abstract: The aim of this research is to prove that when a current carrying cable is suspended at the center of a steel pipe, eddy current is the main energy loss and not joule heating or I <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> R loss. Various experiments were done, sending currents levels of between 54A to 108A in a twisted bare Cu cable or PVC insulated cables within steel and HDPE pipes. The heat loss was measured with two heat measuring instruments which enabled a conclusion to be formed that most of the energy loss is due to eddy current and not Joule heating. As long as the cable is sized higher than the current carrying capacity, there will be negligible Joule heating and the main loss will be eddy current loss.
