TYPE OF TRANSFORMER:
Constructionally Transformer are generally two types, distinguished from each other merely by manner in which primary and secondary coils are placed around the laminated core.
Recent development is spiral-core or wound core type.
Another mean of classifying the Transformer according to the type of cooling employed are 3 types:
oil-filled self cooled
oil-filled water cooled
The Transformer are classified as the voltage ratios from primary to secondary are two types. These are widely used transformer types for all the applications.
ONE ANOTHER TYPE OF TRANSFORMER PRESENCE THAT IS- ISOLATION
Based on usage Transformer are many types as follows:
Based on Rated voltage and current Transformer are two types:
VOLTAGE TRANSFORMER (POTENTIAL TRANSFORMER)
Based on Place of Use Transformer are two types:
Based on Phase Transformer are two types;
Single Phase (1 Phase)
Poly Phase (3 Phase)
3 Phase transformer are 2 in types- a) Delta Type – Δ b) Star Type- Y
