标准摘要
[中文适用范围]： 提供了计算并联布置的单芯电缆中的相电流和环流损耗的方法。本标准中描述的方法可用于任何物理布局中每相并联任意数量的电缆。该 p [外文原描述]： 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 method for calculating sheath eddy current losses in two circuits in flat formation is given in IEC 60287-1-2.
