This standard applies to dry-type and oil-immersed type, three-phase and single-phase power transformers with power ratings from 10 kVA to 2500 kVA and system highest voltage up to 24 kV. This standard does not apply to certain categories of special transformers such as—

  1. transformers other than those on 11 or 22 kv networks;

  2. instrument transformers;

  3. auto transformers;

  4. traction transformers mounted on rolling stock;

  5. starting transformers;

  6. testing transformers;

  7. welding transformers;

  8. three phase transformers with three or more windings per phase;

  9. arc-furnace transformers;

  10. earthing transformers;

  11. rectifier or converter transformers;

  12. uninterruptible power supply (ups) transformers;

  13. transformers with an impedance less than 3% or more than 8%;

  14. voltage regulating transformers;

  15. transformers designed for frequencies other than 50 hertz;

  16. gas-filled dry-type transformers; or

  17. flameproof transformers.
