Description
An auto transformer is a type of electrical transformer that shares a common winding for both the primary and secondary circuits, instead of having separate windings. It is primarily used for voltage regulation or step-up/step-down voltage conversion in various electrical applications.
Key Features:
- Construction:
- The visible cylindrical windings are made of copper or aluminum, with varnish insulation for protection and durability.
- The yellow end caps might be used for mounting or insulation.
- Operation:
- Unlike conventional transformers, an auto transformer is more compact and efficient, requiring less material (like copper) due to the shared winding design.
- Applications:
- Voltage regulation for equipment.
- Motor starting for industrial machines.
- Power distribution where efficiency and size matter.
These transformers are widely used in industries, power distribution networks, and laboratories for their ability to efficiently adjust voltage levels.
