How to use current transformer

WebA current transformer (CT) is an instrument transformer that works based on the principle of electromagnetic induction. It is used to measure the current flowing in a power system circuit or an electrical device without disconnecting the conductor. A CT typically consists of a primary winding, a secondary winding, and a magnetic core. WebA “current output” CT needs to be used with a burden resistor. The burden resistor completes or closes the CT secondary circuit. The burden value is chosen to provide a voltage proportional to the secondary current. The …
