Kabllot elektrik - Llogaritja e vlerësimit të rrymës - Pjesa 1-3: Ekuacionet e vlerësimit të rrymave (faktori i ngarkesës 100%) dhe llogaritja e humbjeve - Ndarja e rrymave ndërmjet kabllove një dejësh paralel dhe llogaritja e humbjeve të rrymave qarkulluese
Electric cables - Calculation of the current rating - Part 1-3: Current rating equations (100 % load factor) and calculation of losses - Current sharing between parallel single-core cables and calculation of circulating current losses
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.
