There are some basic and major differences between a power transformer and a distribution transformer. A power transformer is used in transmission work of higher voltages involved in the step-up and step-down application and is mostly rated above 200kVa. However, a distribution transformer is used for lower voltage distribution networks mainly to end user connectivity. The voltages associated with power transformer are 400kva, 200kva, 110kVa, 66kva, 33kva usually whereas in case of distribution transformer the voltage ranges from 11kVa, 3.3kVa, 200v to 100V. Distribution transformer price in India varies greatly depending upon a lot of factors.
Power transformers are mostly used for the transmission of heavy voltage load and have greater efficiency. These are very big in size as compared to distribution transformers and for this very reason, they are used in generating stations and transmission substations. Distribution transformers are used for the transmission of electricity at a voltage less than or up to 33kV for industrial purposes and 440-220V for domestic purpose. The efficiency for distribution transformers is 50-60% which is also very low when compared to the power transformers which is around 100%. Distribution transformers are very easy to install and are small in size. It is not always fully loaded.
Power transformers are used in the transmission network hence they do not directly connect to the customers, thereby leading to very low load fluctuations. The iron and copper loss is very less as it gets loaded fully during the day. It has a high average load somewhat near to fully loaded transformer thus, it is designed in a way to provide maximum efficiency. These transformers are independent of time so, only power basis is enough for calculating the efficiency. In the distribution network, there is a direct connection to the customers so load fluctuation is very high. Iron losses take place throughout the day whereas copper losses depend on the road cycles. Distribution transformers are not fully loaded. It gives maximum efficiency at 75%of full time.
The power transformers are used for transmission networks to minimize the l2r losses for specific power flow. The power transformers are designed specifically to utilize the core to its maximum level and operate more or less near the knee point of the B-H curve. It helps in bringing down the masses to the core enormously. These transformers can naturally match the iron loss and copper loss at its peak load. A distribution transformer is not designed in a similar way. Therefore, the all-day efficiency of these transformers is dependent on the way it is designed. It also depends on the load cycle for which it has to supply. List of distribution transformer manufacturers in India provides a core design that not only takes care of the peak loads but also maintains an all day long efficiency. Thus it works as a bargain between the two points. Power transformers are designed in a way to operate at a full load and hence designed such that copper losses are minimized. In a power transformer, the flux density is high as compared to the distribution transformer.
