scope:
This section of IEC 287-1 provides a method for calculating the eddy current losses in the metallic sheats of single-core cables arranged as a three-phase double circuit in flat formation. The sheaths are bonded at one point or are cross-bonded so that there are no significant sheath circulating currents. Where metallic sheats are bonded at both ends, there are significant circulating currents which result in a lower current-carrying capacity. A method of calculating circulating current losses for double circuits is under consideration.
