The function of a current transformer is to ensure the safe and economical operation of power systems; it is necessary to monitor and measure the operating conditions of electrical equipment. However, ordinary measurement and protection devices cannot be connected directly to high-voltage primary equipment, so it is required to convert the high currents in the primary system into lower currents on a proportional basis, so that they can be used by measuring instruments and protection devices.

A current transformer converts the high current on the primary side into a lower current on the secondary side, based on the principle of electromagnetic induction, and is used for purposes such as protection and measurement.

The function of a transformer is to reduce alternating voltage and high currents proportionally to values that can be directly measured by instruments, thereby facilitating direct measurement by these instruments; it also provides power for relay protection and automatic control devices.

The function of a transformer is to reduce alternating voltage and high currents in proportion, so that the values become measurable directly by instruments, thereby facilitating direct measurement by these instruments. It also provides power for relay protection and automatic control devices. Transformers used in power systems are special types of transformers that transmit information about the high voltage and large currents in the power grid to the low voltage and small current secondary side, where metering instruments, relay protection devices, and automatic control systems are located. They serve as linking elements between the primary system and the secondary system; the primary winding is connected to the power grid, while the secondary windings are connected to measuring instruments, protection devices, and other components. Together with measuring instruments and metering devices, transformers can be used to measure the voltage, current, and electrical energy in the primary system ； In combination with relay protection and automatic devices, it can provide electrical protection and automatic control for various faults in the power grid. The performance of transformers directly affects the accuracy of measurement and metering in power systems, as well as the reliability of the operation of relay protection devices.
