Analysis and Application of Non-contact Wide-frequency Voltage Measurement Technology

In recent years, the continuous development and increasing complexity of power systems have imposed higher demands on voltage measurement technologies. This paper first provides a comprehensive analysis of several typical non-contact wide-frequency voltage measurement methods, focusing on their principles, methodologies, and applications. Following this, the application of non-contact wide-frequency voltage measurement technology in power system monitoring and protection is discussed. The analysis reveals that non-contact voltage measurement technology significantly enhances the safety and reliability of power systems and demonstrates broad prospects in practical applications.
