Technical losses can be reduced by use of energy efficient transformer in Transmission and Distribution system.
1. The energy efficient transformers have low loss materials (core and winding), and are designed optimally to give the best performance. 2. Reduction in magnetizing current leads to lower losses again. 3. Due to the low loss core (amorphous core) materials the iron losses are reduced by around 70 % leading to increase in the all day efficiency. 4. Also the resin cast transformers have low losses due to which their efficiency rises to 98 % even at low loads especially for distribution transformers. 5. It may be higher for power transformer. Thus the overall transmission & distribution efficiency improves.
