A dry-type transformer is a type of transformer that does not use liquid coolant for insulation and cooling. Instead, it relies on air as the cooling medium and solid insulation materials to provide electrical insulation. Dry-type transformers are widely used in various applications and offer several advantages over liquid-filled transformers, making them popular in both industrial and commercial settings.

Working Principle

Dry-type transformers operate on the same fundamental principles as other transformers. They transfer electrical energy from one circuit to another through electromagnetic induction. The transformer consists of two or more coils of wire, known as windings, that are wound around a core made of laminated steel.

The primary winding receives the electrical energy from the power source and generates a magnetic field when an alternating current (AC) flows through it. This magnetic field induces an alternating voltage in the secondary winding, which is connected to the load. The secondary winding delivers the transformed voltage to the load, enabling the transfer of electrical power.
