Electric cables. Calculation of the current rating - Current rating equations (100 % load factor) and calculation of losses - Current sharing between parallel single-core cables and calculation of circulating current losses Ingestion-build-135476 This part of ISO 168901 Scope This part of IEC 60287 provides a method for calculating the phase currents and circulating current losses in single core cables arranged in parallel. The method described in this standard can be used for any number of cables per phase in parallel in any physical layout. The phase currents can be calculated for any arrangement of sheath bonding. For the calculation of sheath losses, it is assumed that the sheaths are bonded at both ends. A
