Question 20 -0.519886 radians How come= tan–¹ = (0.0291566) = 1.6704 Use maclaurin series formula ( in radians) Question 19 A (medium) single phase transmission line 100 km long has the following constant , resistance per kilometer 0.25 ohm , reactance per kilometer 0.8 ohm , susceptance per kilometre 14×10–⁶ siemens, receiving end line voltage 66 kv , Asuming that the load capacitance of the line is localised at the receiving end alone . determine (1) the sending end current (2) the sending end voltage (3) regulation {4) supply power factor . the line is delivering 15000 kilowatt at 0.8 power factor lagging . Draw the phasor diagram to illustrate your calculations . ...
