What is Current Transformer(CT)? ,Function Of CT,Construction of CT,Ratio of CT,Working Principle of CT,Uses /Advantages and Disadvantages of CT
Introduction A Current Transformer(CT) is a type of transformer that is used to reduce or multiply an alternating current (AC) (used along with measuring or protective device).It produces a current in its secondary which is proportional to the current in its primary. Function of Current Transformer The current transformers are basically a step up transformers.In case of high magnitude supplies we can not connected the measuring devices directly.we used current transformer to the supply of those devices with currents of magnitude proportional to these of power.Current transformer also isolates the measuring instruments from the high voltage circuits.current transformers supply the protective relays with current of magnitude proportional to those of power circuit but sufficiently reduce in magnitude.
