1 2606in transmission line, if the load is suddenly increased at the receiving end of the system the phase shift will (a)decrease (b)becomems zero (c)increase (d)not be affected
4 7603two parallel conductors are carrying the current in the same direction.which of the following statements is true? (a)there is arepelling force between the conductors (b)the force increases when the distance between the conductors is increased (c)there is an attaracting force between the conductors (d)the force increases when the distance between the conductors is decreased
1 3171In the solution of load flow eqation, Newton raphson method is superior to the gauss siedal method because (a)the time taken to perform one iteration in the NR method is less when compared to GS method (b)the number of iterations required in the NR method is more compared to that in the GS method (c)the number of iterations required is dependant on the size of the system in the NR method (d)convergence characteristics of the NR mehod are not affected by the selection of the slack bus
1 3871the transient state stability limit of a system wherin power is transmitted throgh a double transmission line is (a)equal to steady state stability limit (b)more than its steady state stability limit (c)less than than its steady state stability limit (d)equal to its dynamic stability limit
