An overhead line having the surge impedance of 400 Q is connected to a short length of cable of surge impedance of 50 Q. A travelling wave of constant magnitude of 80 kV and infinite duration originates in the overhead line and travels towards the junction with cable. Find the energy transmitted for a duration of 3 usec into the cable after the wave has arrived at junctions.

Compensation Techniques

The compensation techniques are the methods that are employed in the electrical control systems to enhance the performance of the system. The performance are generally affected by the factors like lag in the compensating devices, slow response of the system of the components like sensors used in the control system. The basic compensation technique involves lag compensation, lead compensation or the combination of the both.
