Where and why are isolation transformers used?Johnson Electric Coil Company
In contrast, the isolation transformer, by its very nature, affords a degree of electrical safety/protection to people and equipment alike that the autotransformer cannot provide. And, unlike an autotransformer, an isolation transformer can accommodate an electrostatic shield between input and output, which a) prevents electrical noise on the load side from filtering back onto the line side, b) provides an additional degree of isolation between input and output windings, and c) can provide for an electrical path to ground, or protective earthing, in the event of a fault. Isolation transformers, like autotransformers, can be used to create a step up or step down. The isolation transformer can also mitigate potentially damaging effects of poor power quality on sensitive equipment over time.
