What is the purpose of an isolation transformer?
An isolation transformer is a type of transformer used to decouple two circuits. It allows a current to flow between the two circuits without directly connecting them. It serves several useful functions.Blocks DC CurrentLike other transformers, an isolation transformer prevents the flow of direct current power from one circuit to another. It allows only alternating current through.Blocks InterferenceAn isolation transformer is specially shielded to prevent the transmission of any interference, such as minor variations in voltage that may be caused by the structure of the transformer.Protects Delicate DevicesIsolation transformers protect the devices connected to them from any damage that could be caused by variations in voltage. As a result, they are often used in computer power supplies or with other delicate electronic devices.Reduces Shock RiskIn repairing an electrical device, there is a risk of harmful electric shocks.
