CURRENT TRANSFORMER MSQ 40
A current transformer (CT) MSQ is a type of electrical transformer that is designed to measure alternating current (AC) in electrical power systems. It is used to provide a reduced-scale replica of a large electrical current for the purpose of measuring and protecting electrical power systems.
A current transformer consists of a primary winding, a secondary winding, and a core, which is typically made of a ferromagnetic material such as iron. The primary winding is connected in series with the electrical current being measured, and the secondary winding is used to provide an output current that is proportional to the primary current, but at a lower magnitude.
The current transformer produces an output current that is proportional to the primary current, with the proportionality factor being the turns ratio between the primary and secondary windings. For example, if the turns ratio is 100:1, the output current will be 1/100th of the primary current.
Current transformers are commonly used in electrical power systems for metering and protection purposes. They are used in combination with a meter or a protective relay to measure or protect against electrical fault conditions in the power system.
