A current transformer (CT) is a type of transformer that is used to reduce or multiply an alternating current (AC). It produces a current in its secondary which is proportional to the current in its primary. Current transformers, along with voltage or potential transformers, are instrument transformers. Instrument transformers scale the large values of vol… Then to summarise, the Current Transformer, (CT) is a type of instrument transformer used to convert a primary current into a secondary current through a magnetic medium. Its secondary winding then provides a much reduced current which can be used for detecting overcurrent, undercurrent, peak current, or … See more The Current Transformer ( C.T. ), is a type of instrument transformer that is designed to produce an alternating current in its secondary winding which is proportional to the current being … See more The secondary winding will supply a current into either a short circuit, in the form of an ammeter, or into a resistive load until the voltage … See more There are three basic types of current transformers: wound, toroidal and bar. There are many specialized types of current transformers now available. A popular and portable type which can be used to measure … See more Unlike a voltage transformer, the primary current of a current transformer is not dependent of the secondary load current but instead is controlled by an external load. The secondary current is usually rated at a standard 1 … See more http://learnmetering.com/ct-meter/ bishop texas newspaper
