Example 9.7: Three single core lead sheathed cables carry three-phase current of 400 A. The nominal conductor area of the cores is 1.25 sq. cm, the sheath thickness is 0.152 cm and the diameter over the sheath is 2.28 cms. They are supported in equilateral formation with a distance between cable centres of 5.08 cms. Calculate the induced e.m.f. in each sheath when the cable is 2 km long and supply is 50 Hz. 5.08 cm 0.152 cm 2.28 cm Fig. E.9.7
