How Does a 2000kVA Transformer Work?
The operation of a transformer is based on 전자기 유도.
Simple Working Process:
- Alternating current flows into the primary winding
- A magnetic field is created in the core
- This magnetic field induces voltage in the secondary winding
- Voltage changes according to the turns ratio
Basic Formula:
- 전압비 = 권선비
- 전력은 거의 일정하게 유지됩니다. (minus losses)
This simple principle allows efficient transmission of electrical energy over long distances.
