TM is a trade mark that is not yet registered.
R in a circle denotes a registered trade mark.
A service mark is a trademark applied to a service, whereas a trademark is applied to a product.
And a C in a circle means that it is copyrighted, and cannot be used without permission from the owner of the copyright.

Before we have any more suggestions, a little more information about where on the transformer the symbol was found might go a long way to getting an answer. A photo would be even better.
