As one of the infrastructures of modern society, the power system plays a vital role in ensuring national economic development and people's livelihood needs. As an important part of the power system, voltage transformer's performance and accuracy directly affect the operation and management of the power grid. With the continuous development of science and technology, the application of sensor technology in the field of voltage transformers has developed rapidly, providing strong support for the stable operation and intelligent management of power systems.

A sensor is a device that converts non-electrical signals (such as temperature, pressure, light, etc.) into electrical signals. In power systems, the main function of voltage transformer sensors is to convert high-voltage signals into low-voltage signals suitable for use in measurement and protection equipment. Advances in sensor technology directly affect the performance, accuracy and reliability of voltage transformers.

Over the past few decades, traditional voltage transformer sensor technology has been primarily inductive or capacitive designs. To a certain extent, these traditional designs have problems such as low accuracy, slow response speed, large size, and heavy weight, making it difficult to meet the power system's requirements for accurate measurement and rapid response.

With the continuous advancement of science and technology, various new sensor technologies have been introduced into voltage transformers, making it possible to improve and optimize their performance. Microelectromechanical system sensor is a miniature sensor manufactured using micromachining technology. It has the advantages of small size, low power consumption, and fast response speed. In voltage transformers, MEMS sensors can achieve high-precision, real-time monitoring of voltage, and can adapt to complex working environments. Fiber optic sensor is a sensor that uses optical principles to detect changes in environmental parameters. In power systems, optical fiber sensors can realize remote monitoring of voltage. They have the advantages of anti-electromagnetic interference, high precision, and large measurement range. They are suitable for voltage measurement in special environments such as high voltage and large current. Magnetostrictive sensor is a sensor that utilizes the magnetostrictive effect of magnetic materials to achieve displacement measurement. Among voltage transformers, magnetostrictive sensors can achieve accurate measurement of voltage and have the advantages of small size, fast response speed, and strong anti-interference ability. They are suitable for applications in harsh environments such as high voltage and high temperature.

The new sensor technology uses advanced sensing principles and manufacturing processes to achieve high-precision measurement of voltage and meet the power system's need for accurate monitoring. The new sensor technology has strong anti-interference ability and stability, can operate stably for a long time in harsh working environments, and ensures the safe operation of the power system. The new sensor technology has a fast response speed, can realize real-time monitoring and rapid response to voltage changes, and improves the dynamic response capability of the power system.

The advancement of voltage transformer sensor technology provides strong support for the intelligent management and safe and stable operation of power systems. With the continuous development of science and technology, we have reason to believe that new sensor technology will play an increasingly important role in the field of voltage transformers, injecting new vitality and power into the future development of power systems.
