What is ct transformer

Question

Accepted Answer

A CT transformer, also known as a current transformer, is an electrical device used to measure alternating current (AC) by stepping down the current to a lower value.

CT transformers are commonly used in power systems to measure high currents without directly connecting measuring instruments to the circuit.
They consist of a primary winding, which carries the current to be measured, and a secondary winding, which is connected to the measuring instrument.
The secondary winding of a CT transformer typically has a much larger number of turns than the primary winding, resulting in a reduced current.
The ratio of primary to secondary turns determines the transformation ratio and the amount of current reduction.
CT transformers are often used in conjunction with protective relays to detect faults and abnormal conditions in power systems.
They are also used in energy management systems, power quality monitoring, and metering applications.
For example, in a distribution transformer, a CT transformer is used to measure the current flowing through the primary winding and provide feedback for control purposes.
