High voltage power transformers are transformers that operate at high voltage levels. Transmitting current at high voltage levels can not only improve transmission efficiency but also save time and cost; It can also use lighter and thinner cables to reduce the cost of wire construction. There are some differences in the high voltage range under different standards. In general, the high voltage range is 115-230kV. The maximum transmission voltage used in China is 1000kV, and the maximum transmission voltage used in the United States is 500kV.

The operation of the high voltage transformer is based on the principle of electromagnetic induction. The primary winding and secondary winding are wound around the iron core constituting the closed loop. When the primary winding is applied with AC voltage, alternating magnetic flux is generated in the iron core. The alternating magnetic flux induces an electromotive force in the primary and secondary windings because the turns of the primary and secondary windings are different Therefore, the magnitude of the induced electromotive force at the primary and secondary sides is different, thus realizing the purpose of voltage transformation. The more coil turns, the higher the output voltage. Therefore, the volume of the high voltage transformer is larger.

1. Use high-voltage side sampling to directly obtain current, voltage, and waveform data, which is true and accurate.

2. Over-voltage protection: When the output exceeds the set voltage limit, the high-voltage transformer will stop protection, and the running time is less than 20ms.

3. Overcurrent protection: specially designed for high and low-voltage dual protection environments, precise shutdown protection can be set on the high voltage side; the development of protection will stop if the current on the low-voltage side exceeds the rated current, and the cost of work and study time is less than 20 milliseconds.

4. The booster body is designed with a high-voltage output protection resistor, so there is no need to connect an external protection resistor.
