The types of electrical transformers differ depending on their purpose, use, and construction as follows:

Step Up Transformer and Step Down Transformer: It is generally used to increase the voltage level in the power transmission and distribution network.
Distribution Transformers and Instrument Transformer: Power transformers are generally used in transmission network in order to raise or lower the voltage level. It works mainly during high or peak loads, and has maximum efficiency near full load. Distribution transformer reduces voltage for distribution purpose to domestic or commercial users. It has good voltage regulation and runs 24 hours a day with maximum efficiency at 50% at full load.
Autotransformer: It is generally used where the ratio between high voltage and low voltage is greater than 2. It is cost-effective for later use where the ratio between high voltage and low voltage is less than 2.

Outdoor and Indoor Transformers - Transformers designed for outdoor installation are outdoor transformers and transformers designed for indoor installation are indoor transformers.
