Welcome to your Power Systems
A three phase 50 Hz line consists of three conductors each of diameter 21 mm, The spacing between the conductors all follows: A – B = 3m, B – C = 5m, C – A = 3.6m If the line operates at 132 k V, the reactive voltampere generatd by the line per km is
A 3-phase, 11 kv, 50 Hz, 200 kW load has a power factor of 0.8 lag. A delta connected 3-phase capacitor is used to improve the power factor to unity. The capacitance per phase of the capacitor in micro-farads is
58)Bulk power transmission over long HVDC lines are preferred on account of
The conductor of a 10 km long, single phase, two wire line are separated by a distance of 1.5 m. The diameter of each conductor is 1 cm, If the conductors are of copper, the inductance of the circuit is
