Indoor fully enclosed 10kV high voltage transformer

In order to transmit electrical energy, the power system often uses AC voltage and high current circuits to send electricity to users, which cannot be directly measured with instruments. The function of a transformer is to proportionally reduce the AC voltage and large current to values that can be directly measured by instruments, facilitating direct measurement by instruments, and providing power for relay protection and automatic devices. The transformer used in the power system is a special type of transformer that transmits high voltage and high current information from the power grid to the secondary side of the low voltage and low current metering and measuring instruments, as well as relay protection and automatic devices. It is a connecting element between the primary and secondary systems, with the primary winding connected to the power grid and the secondary winding connected to the measuring instruments, protection devices, etc. The transformer, in conjunction with measuring instruments and measuring devices, can measure the voltage, current, and electrical energy of the primary system; Combined with relay protection and automatic devices, it can form electrical protection and automatic control for various faults in the power grid. The performance of the transformer directly affects the accuracy of measurement and metering in the power system, as well as the reliability of relay protection device operation.
