CLASSIFICATION OF TRANSFORMER

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.

  1. CORE TYPE

  2. SHELL TYPE

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:

  1. oil-filled self cooled

  2. oil-filled water cooled

  3. air-blast type

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.

  1. STEP-UP

  2. STEP-DOWN

ONE ANOTHER TYPE OF TRANSFORMER PRESENCE THAT IS- ISOLATION

Based on usage Transformer are many types as follows:

  1. POWER TRANSFORMER

  2. DISTRIBUTION TRANSFORMER

  3. MEASUREMENT / INSTUMENT TRANSFORMER

  4. PROTECTION TRANSFORMER

Based on Rated voltage and current Transformer are two types:

  1. CURRENT TRANSFORMER

  2. VOLTAGE TRANSFORMER (POTENTIAL TRANSFORMER)

Based on Place of Use Transformer are two types:

  1. INDOOR TRANSFORMER

  2. OUTDOOR TRANSFORMER

Based on Phase Transformer are two types;

  1. Single Phase (1 Phase)

  2. Poly Phase (3 Phase) 

3 Phase transformer are 2 in types- a) Delta Type – Δ            b) Star Type- Y

ONE ANOTHER TYPE OF TRANSFORMER WIDELY USED THAT IS AUTO TRANSFORMER- IT IS A SINGLE WINDING TRANSFORMER
