DC Immune Toroidal Current Transformer

DC Immune Toroidal Current Transformer

The toroidal current transformers, or ring type CTs, can be applied for many applications where primary wires or busbars already exist. As the composite core of high grade is adopted, the DC immune error is less than 3%.
