brief introduction: Current sensors are devices used to measure the flow of current in an electric circuit. They can also be referred to as current transducers or current sense transformers. They are available in a variety of types for measuring AC and DC current flows, including: Hall effect, Rogowski coils and transformers. Current sensors do not have a direct electrical connection to the current being monitored allowing for galvanic isolation to the measurement circuit. Current sensors operate in either open or
