In power systems and industrial applications, reactors are crucial for reactive power compensation and current limiting, making their reliability and stability essential. However, in humid or variable climates, condensation can form inside reactors, reducing insulation performance insulation performance and potentially causing short circuits or equipment damage. This article explores how proper Ingress Protection (IP) rating design and supporting measures can effectively prevent condensation in reactors operating in humid conditions. It also introduces internationally recognized protection standards and practical methods to help users select and maintain suitable reactor products for damp environments. Content 1.
