Calculate the all-day efficiency of a 100-kVA transformer operating under the following conditions: 6 hours on a load of 50 kW at 0.73 power factor; 3 hours on a load of 90 kW at 0.82 power factor; 15 hours with no load on secondary. The iron loss is 1,000 Watts and the full-load copper loss is 1, 060 Watts.

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.
