Frequently Asked Questions
A power transformer uses electromagnetic induction. When AC flows through the primary coil, it creates a changing magnetic field in the core, which induces a voltage in the secondary coil.
They are essential in:
- Power generation: Step up generator voltage (e.g., 10–35kV to 110kV+) for efficient long-distance transmission.
- Transmission & substations: Convert voltage levels between grids.
- End-user supply: Step down high voltage to 380V/220V for industrial and residential use.
Also widely used in railways, solar/wind farms, and data centers.
- By function: Step-up, step-down, autotransformer, isolation.
- By cooling: Oil-immersed (high-capacity, outdoor) and dry-type (indoor, fire-resistant).
- By phase: Single-phase (small loads) and three-phase (industrial/grid use).
- By winding: Two-winding, three-winding, or auto-connected.
