33kv 415v transformer specification

33kv 415v transformer –

A 33kV/415V transformer is a step-down transformer used to convert high-voltage power from the grid (33kV) to lower-voltage power for distribution (415V)

specifications-

  1. Rated power: 1000 kVA (kilovolt-ampere) or higher depending on the application
  2. Input voltage: 33 kV (kilovolts)
  3. Output voltage: 415 V (volts)
  4. Phases: Three-phase
  5. Frequency: 50 Hz or 60 Hz depending on the country
  6. Cooling method: Oil-immersed with natural air cooling or forced air cooling
  7. Insulation class: Class A or Class F
  8. Tap changer: Off-circuit tap changer or on-load tap changer with +/-5% or +/-2.5% voltage regulation depending on the application
  9. Efficiency: Typically between 98% and 99% depending on the load and operating conditions
  10. Vector group: Yyn0 or Dyn11 depending on the application and connection method
  11. Standards compliance: IEC (International Electrotechnical Commission) standards for power transformers or local standards depending on the country of use

 

Note:- 33kV/415V transformer can vary depending on the manufacturer, application, and specific requirements of the project
