Transformer Tests

The reliability, performance, and suitability of transformers for operating conditions are verified through tests conducted at various stages of the production process. At Deltasan, transformers undergo routine, type, and special tests in accordance with applicable standards and technical specifications.

Routine Tests

Routine tests are carried out to verify that every transformer manufactured meets the relevant technical requirements and design criteria.

• Measurement of winding resistance

• Measurement of insulation resistance

• Measurement of the transformer turns ratio and determination of the connection group and polarity

• Induced voltage test

• Applied voltage test

• Measurement of no-load losses and no-load current

• Measurement of load losses and impedance voltage

• Transformer oil breakdown voltage test

• Leakage test

Type Tests

Type tests are carried out to verify that the transformer design complies with specified standards and performance criteria. These tests include comprehensive checks to evaluate the transformer's durability and performance under various operating conditions.

• Temperature-rise test

• Lightning impulse voltage test

• Short-circuit withstand test

• Measurement of audible noise level

• Mechanical withstand test against short circuits

• Transformer tank life test

Special Tests

Special tests are additional checks performed in line with customer requests, project requirements, or applicable technical specifications.

• Measurement of capacitance and insulation dissipation factor (Tan Delta / Double Test)

• Measurement of coating thickness

Through the tests performed, Deltasan verifies the reliability, durability, and performance criteria of transformers and aims to provide products that meet project requirements.
