Isolation Transformer

However, the term “Isolation Transformer” is used to differentiate the special type transformers that are used to protect electrical equipment from spikes and surges. The term “isolation” is generally used to specify that the transformer is used for isolation of electricity between the input and output of the transformer.

The devices that are known as Isolation Transformers, use separate bobbins for the primary and secondary coil windings. The secondary winding is kept isolated (floating) from the primary.
