“…Again, exact calculation of this for bi-pole DC cables is beyond the scope of this paper; part of the method is outlined in [7]. Similar results for other cable configurations given in [5] (monopole DC cable) and [9] (single core and three core AC cables) suggest that the value of inductance for cables at 1kHz is significantly reduced compared to the DC (or fundamental AC) value.…”

“…In comparison to its DC value, the inductance of the cable at 1kHz is reduced, again due to skin and proximity effects [7,8]. Again, exact calculation of this for bi-pole DC cables is beyond the scope of this paper; part of the method is outlined in [7].…”

“…In particular, (2) does not include the additional reactance due to the presence of the armor (34 nH/m for our sample cable); and eddy current losses are not negligible, although they are approximately proportional to those due to circulating current. Clause 2.4.2.5 of IEC 60287-1-1 defines an equation for the armor loss factor as (3) where is the ac resistance of the armor , is the distance between the axis of a conductor and the cable center (in millimeters), and is the mean diameter of the armor (in millimeters). In addition to the industry view that the losses predicted by (3) are too high, we have identified some theoretical reasons for doubting the validity of (3).…”

“…Наличие достаточно сильной анизотропии маг-нитной проницаемости материала является одним из факторов, которые необходимо учитывать при расче-те потерь на продольные и вихревые токи в прово-лочной броне силовых кабелей [1][2][3]. В качестве при-мера одного из таких типов кабелей можно привести одножильный силовой кабель типа МНСК.…”
