Voltage transformer is a special transformer, its main function is to convert high voltage into standard, low voltage, in order to measure and protect electrical equipment. Its working principle and characteristics are as follows:

The development of the power industry has promoted the production and application of transformers. The level and accuracy of transformers have also been greatly improved. There are more and more types of transformers, such as voltage and current composite transformers, DC current transformers, etc. More and more. However, in the power industry, the transformer used must be consistent with the use of the power system, and the corresponding voltage level and accuracy of the transformer must be developed for the measurement, protection and control of the power system.

You may have heard of the current transformer, it is a commonly used equipment. The function is to convert a large primary current into a small secondary current through a certain transformation ratio for protection, measurement and other purposes. For example, a current transformer with a transformation ratio of 400/5 can convert a current of 400A into a current of 5A.
