Basic knowledge of transformers

Transformer is a connecting element between the primary and secondary systems in the power system, which can reduce the high voltage and high current in the primary circuit, and then supply power to the voltage coils and current coils of measuring instruments and relays respectively. Can accurately reflect the normal operation and fault situation of electrical equipment
Transformers are mainly divided into two categories: voltage transformers and current transformers. The function of a voltage transformer is to convert high voltage into low voltage, facilitating the use of measuring instruments and relay protection devices. Current transformers, on the other hand, convert large currents into small currents to provide current information for measuring and metering devices in the power grid.
In practical applications, transformers can ensure the safe and stable operation of power systems, improve the quality of power supply, and reduce the occurrence of electrical accidents. At the same time, transformers also provide important technical support for monitoring, control, protection, and other aspects of the power system.
