Advanced Oil-Filled Transformer for Smooth Integration with Grids
Product Description
For each transformer are prepared and issued a test report, in accordance with International Standards. except for routine tests, we also offer type tests and specialised tests to meet all customer requirements. We make what matters work for our customers in a safe and reliable way.
Routine test
- Measurement of winding resistance
- Measurement of voltage ratio and check of phase displacement
- Measurement of short-circuit impedance and loss
- Measurement of no-load loss and current
- Dielectric routine tests
- Tests on on-load tap-changers, where appropriate
- Leak testing with pressure for liquid-immersed transformers(tightness test)
- Tightness tests and pressure tests for tanks for gas-filled transformers
- Check of the ratio and polarity of built-in current transformers
- Check of core and frame insulation for liquid immersed transformers with core or frame insulation
