Why Do Reactors Overheat and Burn Out? —Top Causes and Effective Solutions
As global energy demands surge and power systems grow more complex, reactors (critical devices for reactive power compensation and harmonic suppression) play a vital role in grid stability. However, frequent reactor failures, particularly overheating, have become a costly challenge. According to the International Energy Agency (IEA), 22% of global industrial power outages are caused by reactor burnout, with 75% of failures linked to thermal runaway. This results in annual losses exceeding $10 billion. This article explores the root causes of reactor overheating and offers proven solutions to reduce maintenance costs by 30%-50% annually, aligning with IEC 60076-27 and IEEE C57.21 standards.
