Assume that a single-conductor belted cable has a conductor diameterof 0.681 in., inside diameter of sheath of 1.7025 in., and a length of8000 ft. The cable is to be operated at 12.47 kV. The dielectricconstant is 4.5, and the power factor of the dielectric at a ratedfrequency and temperature is 0.05. Calculate the following:(a) Capacitance of cable.(b) Charging current.(c) Dielectric loss of cable.(d) Equivalent resistance of insulation.

A single core 66 kVolts cable has a conductor diameter of 2 cm and a sheath of inside diameter 5.3 cm. The cable has an inner layer of 1 cm thick of rubber of dielectric constant of 4.5 and the rest impregnated paper of dielectric constant 3.6. Find the maximum stress in the rubber and in the paper.

Determine the mutual inductance between a very long straightwire and a conducting circular loop of radius “b” m set up “d” mapart on the same plane as shown figure.Problem:

The geometric mean radius of a conductor, having four equal strands with each strand of radius 'r', as shown in the figure below, is r

Amagnetic field is being generated by a current of 2.0A flowing through 180 turns of wire on a core having a reluctance of 210000.0 At/Wb. Determine the flux of the circuit in mWb.

H. W.: The cost of a 2-core feeder cable, including installation is (90 a + 20) per meter and the interest and depreciation charges are 10 per cent. The cable is 2 km in length and cost of energy is 4% per unit. The maximum current in the feeder is 250 A and the demand is such that the current copper loss is equivalent to what would be produced by the full flowing for 6 months. If the resistance of a conductor of 1 square cm and 1 km length is 0.173 Q, calculate the most economical cross-sectional area.
