What is the difference between Insulating, Isolating and Shielded Winding transformers?

Insulating and isolating transformers are identical. These terms are used to describe the isolation of the primary and secondary winding's, or insulation between the two. A shielded transformer is designed with a metallic shield between the primary and secondary winding's to attenuate transient noise. This is especially important in critical applications such as computers, process controllers and many other microprocessor controlled devices. All two, three and four winding transformers are of the insulating or isolating types. Only auto transformers, whose primary and secondary are connected to each other electrically,are not of the insulating or isolating variety.
