  • What is Current Transformer (CT)? Definition, Construction

    Definition: A current transformer is a device that is used for the transformation of current from a higher value into a proportionate current to a lower value. It transforms the high voltage current into the low voltage current due to which the heavy current flows through the transmission lines is safely monitored by the ammeter.

    Answer: In most Instrument Transformer applications where the CT is being used for measurement of amperage magnitude only, the CT will work regardless of direction of current flow through the CT. However, typically the H1 faces source and H2 faces load. (refer to figure below) In applications that look at Phase Angle, compare Phases or use Phase Vector Summation, the direction of current may
