| Power Transformers | Distribution Transformers |
|---|---|
| Power transformer transfers electrical energy in any parts of electrical circuit between generator and primary distribution circuit. | Distribution transformer is a transformer for transferring electrical energy from a primary distribution circuit to a secondary distribution circuit or a consumer circuit. |
| Designed for maximum efficiency of 100%. | Designed for 60-70% efficiency. |
| It is independent of time. | It is time dependent. |
| Power transformers are used in transmission network of higher voltages for step-up and step down application and are generally rated above 200MVA. | Distribution transformers are used for lower voltage distribution networks as a means to end user connectivity and are generally rated less than 200 MVA. |
| Power transformer is greater in size. | Distribution transformer is lesser in size . |
