MGVCL Exam Paper (30-07-2021 Shift 1) A coil having an inductance of 100 mH is magnetically coupled to another coil having an inductance of 900 mH. The coefficient of coupling between the coils is 0.45. Calculate the equivalent inductance if the two coils are connected in series aiding. 730 mH 1270 mH 1135 mH 932 mH 730 mH 1270 mH 1135 mH 932 mH ANSWER EXPLANATION DOWNLOAD EXAMIANS APP Mutual inductance (M) = k*√(L1*L2)k = 0.45M = 0.45*√(900*100*10⁻⁶) = 135 mHLeq = L1 + L2 + 2MLeq = 900 + 100 + 270Leq = 1270 mH
MGVCL Exam Paper (30-07-2021 Shift 1) The expression for voltage regulation of a short transmission line for lagging power factor is given by: ___, where, 'I' is the line current, 'V_r' is the receiving end voltage, 'R' is the line resistance and 'X' is the line reactance. (IR cosφ_r + IX sinφ_r)/V_r (IX cosφ_r - IR sinφ_r)/V_r (IR cosφ_r - IX sinφ_r)/V_r (IX cosφ_r + IR sinφ_r)/V_r (IR cosφ_r + IX sinφ_r)/V_r (IX cosφ_r - IR sinφ_r)/V_r (IR cosφ_r - IX sinφ_r)/V_r (IX cosφ_r + IR sinφ_r)/V_r ANSWER EXPLANATION DOWNLOAD EXAMIANS APP For lagging power factor = (IR*cosφ + Ixsinφ)/VrFor leading power factor = (IR*cosφ - Ixsinφ)/VrZero voltage regulation occurs on leading power factor only.
