What is the difference between power transformers and distribution transformers?

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 .
