What are the basic knowledge points about transformer bushings?
1. Functions of Transformer BushingsThe core function of transformer bushings is to lead the coil leads out to the external environment. They serve both as insulating components between the leads and the oil tank and as fixing devices for the leads.During the operation of a transformer, bushings continuously carry load currents and, in the event of an external short circuit, withstand short-circuit currents. Therefore, transformer bushings must meet the following requirements:Possess specified e

Development Direction of Intelligent Monitoring for Surge Arresters in the Internet of Things Era
1. Current Status and Shortcomings of Online MonitorsCurrently, online monitors are the most commonly used tools for surge arrester monitoring. While they can detect potential defects, they have significant limitations: manual on - site data recording is required, precluding real - time monitoring; and post - collection data analysis adds to operational complexity. IoT - based intelligent monitoring overcomes these issues—collected data is uploaded via the IoT to processing platforms, and

Power System Voltage Level Classification
Power System Voltage Level Classification
What Is a Voltage Class?Definition of Voltage Class:Voltage classes (or voltage levels) refer to a set of standardized rated voltages used in power systems and electrical equipment. A rated voltage is the nominal voltage at which equipment is designed to operate under normal conditions; essentially, a voltage class defines the intended working voltage range for a system or device.Analogy to Consumer Appliances:Household appliances (e.g., refrigerators, TVs) operate at a nominal voltage—typ
