What Is a 1500kVA Transformer?
А 1500кВА трансформатор is an electrical device with a rated apparent power of 1500 киловольт-ампер (кВА). It transfers electrical energy between circuits using electromagnetic induction.
- 1500kVA = 1.5MVA
- It can supply medium to large loads
- Common in industrial plants and commercial buildings
The transformer changes voltage levels while keeping the frequency the same.
How Does a 1500kVA Transformer Work?
The transformer works based on a simple idea: цахилгаан соронзон индукц.
Basic Working Steps:
- AC power flows into the primary winding
- It creates a magnetic field in the core
- The magnetic field induces voltage in the secondary winding
- Output voltage depends on the turns ratio
Key Formula:
- Хүчдэлийн харьцаа = Эргэлтийн харьцаа
- Эрчим хүч бараг тогтмол хэвээр байна (ignoring losses)
This allows safe and efficient power transmission.
