Step-up transformer 208 to 480 Principle of operation

A step-up transformer is a type of transformer that increases the voltage from the primary winding to the secondary winding. In the context of a 208 to 480 volt step-up transformer, it means that the input voltage on the primary side is 208 volts, and the output voltage on the secondary side is increased to 480 volts.

Here’s a brief explanation of how a step-up transformer works:

1. Primary Voltage (208V): The primary winding of the transformer is connected to a source with a voltage of 208 volts. This is considered the lower voltage side.
2. Transformer Action: As alternating current (AC) flows through the primary winding, it creates a magnetic field in the transformer’s core.
3. Secondary Voltage (480V): The secondary winding, having more turns than the primary winding, experiences a higher induced voltage. In a step-up transformer, the secondary voltage is higher than the primary voltage. In this case, it is increased to 480 volts.
4. Output Load: The increased voltage on the secondary side is then used to power devices or equipment that require 480 volts.

Step-up transformers are commonly used in various applications, such as industrial settings, where higher voltages are necessary for certain equipment or machinery.
