Current Transformers

 

A Current Transformer is used in monitoring and/or measuring applications to measure higher current.  The high current primary connection is usually stepped down to a smaller current that can easily be measured.

Current Transformers are made with the secondary coil wound on the core.   The customer will usually insert the primary turn with a lead wire or buss bar through the center of core.  The turn ratio of the component will allow the customer to monitor or measure a smaller current.
