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 measured in its primary.
Definition, Construction, Phasor Diagram & Types - Circuit Globe. Current Transformer (CT) 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.
A C.T “Current Transformer” is a type of instrument transformer designed to step down the current in the secondary for protection and measurement of proportional primary current. These transformers with low range ampere meters are used to measure the current in the high voltage circuits.
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.
The CT ratio is the ratio of primary current input to secondary current output at full load. For example, a CT with a ratio of 300:5 is rated for 300 primary amps at full load and will produce 5 amps of secondary current when 300 amps flow through the primary.
What is Summation Current Transformer: First, current transformer is nothing but a step-up transformer which is used to convert high primary current into less current typically 5 to 1 Amps. It works under faraday’s law of electromagnetic induction. Generally, it is called as in the short form of CT. It is used to sense the line current.
24 Φεβ 2012 · Current Transformer Definition: A current transformer (CT) is defined as an instrument transformer where the secondary current is proportional to the primary current and ideally has zero phase difference.
