Performance of transmission lines 1
Question 38 C alculate A, B,C and D constants of a 3 phase, 50 Hz transmission line 160 km long having the following distributed parameters resistance per kilometer 0.15 ohm , inductance 1.20 × 10–³ henery per kilometre , capacitance 8 ×10–⁹ farad per kilometre , Conductance = 0 Question 34 A 132 KV ,50 Hz , 3 phase transmission line delivers a load of 50 mw at 0.8 power factor lagging at the receiving end. The generalised constants of the transmission line are A=D=0.95 angle 1.4° , B = 96 angle 78° , C = 0.0015 angle 90° Find the regulation of the line and charging current ? Use nominal T method. Question 24 Question 25 Question 23 Question 22 Question 21 = -18.155° or -18.153° to -18°9' Question 20 ...
