Distribution transformers, also known as distribution power transformers, are electrical devices designed to change the voltage levels of electric power for safe and efficient transmission and distribution. They are a crucial component of the electrical power grid and are primarily used to reduce the high voltage generated in power plants and transmission substations to lower voltage levels suitable for distribution to homes, businesses, and other end-users.
Here's how distribution transformers work and where they are used:
1. Voltage Transformation: Distribution transformers transform high voltage electricity from the transmission lines (typically 66 kV to 500 kV) into lower voltage levels (usually 11 kV to 33 kV) suitable for local distribution networks.
2. Power Distribution: The transformed power is then distributed to residential, commercial, and industrial areas through medium-voltage distribution lines.
