Voltage reference is a very important concept in the power system, which refers to the reference value of voltage in the power system used to indicate the magnitude and stability of voltage. The accuracy and stability of the voltage reference have important impacts on the normal operation of the power system and the safety of equipment. In the power system, the voltage reference usually refers to the rated voltage, which is the rated voltage value of the equipment and lines in the system. The accuracy and stability of the voltage reference directly affect the stability and safety of the power system.

Currently, the voltage reference industry is in a rapid development stage. With the continuous development of the power system and the increasing demand for electricity, the requirements for the voltage reference are also increasing. In the past, the voltage reference was mainly achieved through traditional voltage measuring instruments, but with the advancement of technology and the intelligent development of the power system, modern voltage references have begun to develop towards digitalization and intelligence. Modern voltage references usually use digital voltage measuring instruments and intelligent control systems, which can achieve accurate measurement and control of voltage, improving the stability and safety of the power system.

Furthermore, with the development of intelligent and information technology in the power system, the voltage reference industry is also moving towards intelligence. Modern voltage reference systems usually have remote monitoring and control functions, which can achieve remote monitoring and control of voltage, improving the operational efficiency and reliability of the power system. At the same time, the voltage reference system also has data acquisition and analysis functions, which can monitor the changes and trends of voltage in real time, providing important data support for the operation and maintenance of the power system.

In summary, the voltage reference industry is in a rapid development stage. With the continuous development of the power system and the increasing demand for electricity, the requirements for the voltage reference are also increasing. Modern voltage reference systems have the characteristics of digitalization, intelligence, and information technology, which can achieve accurate measurement and control of voltage, improving the stability and safety of the power system. In the future, with the further improvement of the intelligence and information technology level of the power system, the voltage reference industry will have broader development space, providing more reliable support for the safe and stable operation of the power system.
