Meramec’s commitment to quality begins with the selection of only the finest raw materials. The core is the heart of the current transformer. It is critical that the core material provides superior magnetic properties. This insures that the primary and secondary circuits are efficiently linked in phase for the life of the transformer.

The core of a Meramec Current Transformer is made of the finest quality grain oriented electrical grade silicon steel. Our steel is manufactured in the U.S to our exacting standards. These rigorous standards insure the low core loss and high permeability qualities required for accurate transformer performance.
