1. Application of Condition Monitoring Technology in UHV Transmission LinesAt present, the main characteristics of UHV (Ultra-High Voltage) transmission line condition monitoring technology in China are reflected in the following aspects: Comprehensiveness: In general, during the implementation of monitoring technology, supporting facilities and integrated systems are required to ensure effective monitoring performance; High value: UHV transmission line condition monitoring technology is a criti

1 Characteristics and Components of High-Voltage Transmission Lines1.1 Characteristics of High-Voltage Transmission LinesHigh-voltage transmission lines are characterized by their relatively low cost due to the smaller amount of information they require. They typically use two conductors, one connected to the positive pole and the other to the negative pole. DC transmission lines have durability and can transmit current over long distances. In some high-voltage transmission facilities in China,

An insulator is a special type of insulating component that serves the dual purpose of supporting conductors and preventing current from grounding in overhead transmission lines. It is widely used at the connection points between transmission towers and conductors, as well as between substation structures and power lines. Based on the dielectric material, insulators are classified into three types: porcelain, glass, and composite. Analyzing common insulator faults and preventive maintenance meas

Skin Effect DefinedSkin effect in transmission lines is the phenomenon where AC current concentrates near the conductor’s surface, increasing its effective resistance.Skin effect is defined as the tendency of an AC current to distribute unevenly over the cross-section of a conductor, such that the current density is highest near the surface of the skin of the conductor and decreases exponentially towards the core. This means that the inner part of the conductor carries less current than the oute

What is a Transmission Lines?Transmission Line DefinitionA transmission line is a designed conductor that carries large volumes of electrical power across large distances at high voltages.Line Types and LengthsTransmission lines are categorized by length; short lines are under 80 km, medium lines between 80 and 250 km, and long lines over 250 km.Efficiency ExplainedTransmission line efficiency is the ratio of power received to power sent, indicating how much power reaches its destination versus
