In power systems, voltage transformers are vital components and play an important role in monitoring, measuring and protecting the power grid. With the continuous advancement of science and technology and the development of the power industry, voltage transformers have experienced an evolution from tradition to innovation, constantly adapting to the needs of different eras, and in the process showing great development potential and application prospects.

Traditional voltage transformers are usually designed based on the principle of electromagnetic induction, using iron cores and coils to convert high voltage into low-voltage signals that can be measured. This type of voltage transformer has been widely used in power systems and has mature technology and stable performance. However, traditional voltage transformers also have some limitations, such as large size, heavy weight, high installation and maintenance costs, etc., which limit their use in certain application scenarios.

With the continuous development of science and technology, new voltage transformers have begun to emerge and have brought many innovations. Among them, the optical fiber voltage transformer is a typical innovative voltage transformer. Optical fiber voltage transformer uses optical sensing technology and uses optical fiber as a sensing element to reflect changes in voltage by measuring changes in light intensity in the optical fiber. Compared with traditional voltage transformers, optical fiber voltage transformers have the advantages of small size, light weight, and strong anti-interference ability, and can play a role in a wider range of application scenarios.

The emergence of new voltage transformers is not only a technical innovation, but also brings expansion and improvement of the application scope of power systems. For example, in terms of remote monitoring and intelligent control of power systems, optical fiber voltage transformers can achieve remote data transmission and real-time monitoring, providing more reliable support for the safe operation of power systems. In addition, the cost of new voltage transformers is also gradually decreasing, making it easier for them to be widely used in all aspects of the power system.

With the continuous development of the power industry and the acceleration of the intelligentization process, voltage transformers will continue to develop in a more intelligent, efficient and reliable direction. In the future, we can foresee that smart voltage transformers based on artificial intelligence, big data and Internet of Things technology will become an important tool for power system monitoring and control, providing more accurate and reliable support for the operation and maintenance of the power system.

Tradition and innovation are the inexhaustible driving forces for the development of voltage transformers. With the continuous advancement of science and technology and the changing application requirements, voltage transformers will continue to evolve and innovate, constantly adapt to new application scenarios and challenges, and contribute to the safe operation and stable development of the power system. Looking forward to the future, voltage transformers will play a more important role in the construction of intelligent power systems and become the intelligent heart of the power system.
