Current Transformers

Current Transformers (CTs) are electrical devices that are used to measure electrical current in power transmission systems. They are also known as instrument transformers, because they transform the high currents found in power lines into lower currents that can be safely measured by instruments.

The basic principle of a CT is to use the magnetic field generated by the current flowing through a conductor to induce a current in a secondary winding, which is connected to a measuring instrument or a protective relay. The current in the secondary winding is proportional to the primary current, and is typically a lower value, such as 1A or 5A, which is easier to measure.

CTs are typically used in high voltage and high power systems, such as power plants, substations, and industrial facilities, to measure the current flowing through transmission lines, generators, motors, and other equipment. They are also used for protection purposes, such as detecting overcurrents and faults in the system, and triggering circuit breakers to isolate faulty equipment.

CTs come in various shapes and sizes, and are designed for specific current ratings and frequency ranges. They are typically installed around the conductor that carries the current, and connected to the measuring or protective device through insulated leads. Proper installation and maintenance of CTs are critical to ensure accurate and reliable measurements and protection of the system.
