Distribution transformer

Electrical Transformers for Distribution
A distribution transformer is an electrical device that steps down high-voltage electricity from transmission lines to a lower voltage suitable for residential, commercial, and industrial use.

Types of Distribution Transformers
Pole-Mounted Transformers – Small transformers mounted on utility poles, commonly used for residential areas.

Pad-Mounted Transformers – Ground-level transformers enclosed in a locked metal cabinet, used in urban and commercial areas.

Underground Transformers – Used in underground power distribution systems.

Key Features of Distribution Transformers
✅ Step-Down Voltage: Converts high voltage (e.g., 11kV, 33kV) to low voltage (e.g., 400V, 230V).
✅ Oil-Filled or Dry-Type: Oil-immersed for cooling or dry-type for safety in enclosed spaces.
✅ High Efficiency: Typically designed for low energy losses (low iron & copper losses).
✅ Single-Phase & Three-Phase Options: Depending on the application and load requirements.

Applications
🔹 Residential Power Distribution – Supplies homes with 230V/120V power.
🔹 Commercial Buildings & Industries – Provides stable power for operations.
🔹 Renewable Energy Grids – Helps distribute solar and wind-generated electricity.
