A current transformer (CT) is a simple, practical and inexpensive means of detecting the presence of AC current. Detecting load current rather than applied voltage is a superior method of determining ...

“While most current transformers may look the same on the outside, it’s what’s inside that counts,” according to Meramec Instrument Transformer Co. April 29, 2016 “While most current transformers may ...

Current transformers can perform circuit control, measure current for power measurement and control, and perform roles for safety protection and current limiting. They can also cause circuit events to ...
