ELECTRIC CABLES - CALCULATION OF THE CURRENT RATING - PART 1: CURRENT RATING EQUATIONS (100 % LOAD FACTOR) AND CALCULATIONS OF LOSSES - SECTION 2: SHEATH EDDY CURRENT LOSS FACTORS FOR TWO CIRCUITS IN FLAT FORMATION

專家解讀視頻
Gives procedure for calculating the eddy current in the metallic sheaths 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 not significant circulating currents which result in a lower current carrying capacity. The method provides coefficients which are applied as corrections to the loss factors for the sheaths of one isolated three phase circuit. The method should be used for most sizes of aluminium sheathed cable, but is not required for lead sheathed cables unless they are unusually large.
