Question
A. A 200 km line has a resistance of the line per phase per km is 0.08 ohm, a suceptance per phase per km = 6 x 10°-6 ohm and a reactance per phase per km is 0.8 ohm. Using nominal T method, determine the constant B of the line.
A. 153.2 cis 84.6° C. 178.4 cis 81.5°
B. 145.2 cis 88.2° D. 169.5 cis 83.6°
 
 
B) A 132-KV, 50 Hz, 3-phase transmission line delivers a load of 50 MW at 0.8 pf lagging at receiving end. The generalized constant of the line are A = D = 0.95/1.4°; B = 96/7.8°; C= 0.0015/90°. Find the regulation of the line.
A. 23.8 %. C. 29.4 %
B. 25.6 %. D. 27.1 %
