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

Enhancing Power Transformer Resilience in the Face of Climate ChangeClimate change poses significant challenges to power infrastructure, with power transformers—critical components of the electrical grid—particularly vulnerable. As extreme weather events grow more frequent and severe, ensuring the resilience of transformers has become a top priority for utilities and power companies worldwide.Understanding the VulnerabilitiesModern transformers face a growing array of clim ate-relate

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

A substation without a grounding line selection device experienced a single-phase grounding fault. The fault location system (FA) pinpointed the fault section between switch A and switch B. On-site patrol and handling took 30 minutes to isolate the fault, with no need for trial tripping of non-faulty lines.The coordination between the main network and distribution network relies on a comprehensive analysis of "bus protection action, 3U0, three-phase voltage + line terminal alarm". Based on exist

As the frequency and severity of climate-related events such as storms, floods, and wildfires continue to rise, the development of climate-adaptive transformer designs has become an urgent need. Transformers, as a core component of power infrastructure, their ability to withstand extreme weather conditions is directly related to the stability of power supply. This article explores the technical specifications defining climate-adaptive transformer designs, focusing on four key dimensions: materia

1. Indicators Related to the Utilization Rate of Power Transmission TransformersThe utilization rate of power transmission transformers needs to consider both the cost of transmitting and distributing electrical energy and the utilization efficiency of the equipment itself. The core indicators mainly include three dimensions: load rate, load factor, and equipment life rate.1.1 Load RateIt refers to the ratio of the actual load at the moment of maximum load to the rated capacity of the transforme

1. Manifestations of Generator Set Transformer Failures1.1 Abnormal Temperature RiseAbnormal temperature rise directly reflects a transformer’s health and serves as a key fault - warning indicator. During operation, electromagnetic energy conversion causes iron and copper losses, which turn into heat. To ensure normal operation, transformers use heat - dissipation mechanisms like oil circulation and heat radiation to maintain internal temperature balance.Thermometers and online detection s

1 Basic Structure, Operating Characteristics and Special Requirements of Transformers for Wind Power Generation1.1 Basic Structure of Transformers(1) Core StructureTransformers for wind power generation adopt core materials with high magnetic permeability to reduce energy losses. In application, the core usually requires special treatment to adapt to the harsh environment of long - term high humidity and high salinity. Especially in offshore wind farms, the corrosion resistance of the core is pa

At 12:45 on August 4, 2022, a dispatching center received a report from a 100 MW photovoltaic power generation base. It was reported that the incoming line switchgear on the 35 kV low - voltage side of the main transformer at the collection station was on fire, and the protection action tripped. After receiving the notification, relevant personnel went to the site and carried out on - site accident investigation together with the operation technicians. Through on - site inspection, it was found
