1 Failure Mechanisms of Power CapacitorsA power capacitor primarily consists of a housing, capacitor core, insulating medium, and terminal structure. The housing is typically made of thin steel or stainless steel, with bushings welded to the cover. The capacitor core is wound from polypropylene film and aluminum foil (electrodes), and the interior of the housing is filled with liquid dielectric for insulation and heat dissipation.As a fully sealed device, common failure types of power capacitors

1 Overview of Reactive Power Compensation Technology1.1 Role of Reactive Power Compensation TechnologyReactive power compensation technology is one of the widely used techniques in power systems and electrical grids. It is primarily employed to improve power factor, reduce line losses, enhance power quality, and increase the transmission capacity and stability of the grid. This ensures that power equipment operates in a more stable and reliable environment, while also boosting the grid&rsquo

Operation and Maintenance Guidelines for Power CapacitorsPower capacitors are static reactive power compensation devices primarily used to supply reactive power to electrical systems and improve power factor. By implementing local reactive power compensation, they reduce transmission line current, minimize line power losses and voltage drops, and contribute significantly to improved power quality and higher equipment utilization.The following outlines key aspects of power capacitor operation and

Performance Degradation Characteristics and Life Prediction of Power Capacitors under High-Temperature ConditionsWith the continuous expansion of power systems and increasing load demands, the operating environment for electrical equipment has become increasingly complex. Rising ambient temperature has emerged as a key factor affecting the reliable operation of power capacitors. As critical components in power transmission and distribution systems, the performance degradation of power capacitors

Discussion on Operation, Maintenance, and Fault Management of Power CapacitorsPower capacitors play a vital role in power systems by improving voltage quality and enhancing operational efficiency and economic performance. However, during long-term operation, they may experience various failures that affect their performance and reliability, potentially threatening the safety and stability of the entire system. Therefore, in-depth study of their operation, maintenance, and fault handling is essen

Power capacitors are a crucial component in power systems, primarily used to provide reactive power compensation to improve the system's power factor and stabilize voltage, protecting equipment from voltage fluctuations. However, during actual use, power capacitors often face oil leakage issues, which not only degrade their performance but can also pollute the environment and even cause fires or other safety accidents. This significantly affects the lifespan of the equipment and poses a serious
