ISOLATION TRANSFORMER BASICS AND TUTORIALS

ISOLATION TRANSFORMER BASIC INFORMATION
What Are Isolation Transformers? How Isolation Transformer Works?




When servicing any electronic equipment, always use an isolation transformer to protect yourself from an electrical shock. During servicing, the isolation transformer is connected between the equipment and AC power line.

An isolation transformer is a transformer that has a 1:1turn ratio to provide the standard line voltage at the secondary outlet.

This means that it does not change the voltage. The transformer still produces 240 V AC as is outputs, but both sides of this AC lines are independent of ground.

If you were to accidentally touch one of these outputs, you would be protected. The isolation transformer must be rated to handle the power of any equipment connected to it. Typical ratings are 250 to 500 W.

Variable transformer or variacs is not an isolation transformer.
