Distribution transformers are electrical devices designed to step down voltage to a level suitable for powering industrial, municipal, and residential consumers. They serve as a key link between high-voltage substations and local power grids, ensuring a stable and safe supply of electricity.

These transformers operate under constant load, feature high energy efficiency, and ensure minimal power losses. They are used in urban and rural grids, at industrial facilities, in residential complexes, and at commercial sites.

Purpose of Distribution Transformers

Stepping down voltage from high-voltage levels to 6–20–35 kV or lower.

Powering local networks and end users.

Ensuring stable operation of industrial and municipal facilities.

Improving energy efficiency and reducing network losses.

Operation in distribution, compensation, and protection circuits.
