What are the different types of tests related to transformers?

Question

Accepted Answer

Different types of tests related to transformers include routine tests, type tests, and special tests.

Routine tests are performed on every transformer and include measurement of winding resistance, insulation resistance, and voltage ratio.
Type tests are performed on a sample transformer to verify its design and include temperature rise test, impulse test, and short-circuit test.
Special tests are performed on transformers with specific requirements and include noise level test, harmonics test, and partial discharge test.
Other tests include transformer turns ratio test, transformer winding resistance test, and transformer oil test.

Accepted Answer

Types Tests of Transformer are;- Transformation ratio test, Winding resistance test of transformer, Measurement of core losses and no-load current through open-circuit test, Measurement of short circuit impedance and copper losses through short-circuit test, Transformer vector group test, Measurement of insulation resistance
