Introduction<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\tSubstation isolators play a critical role in ensuring the safe operation of electrical power systems. These mechanical switching devices are used to isolate equipment for maintenance and ensure zero current flow during servicing.\nHowever, like any electrical equipment, isolators are prone to operational and mechanical issues if not properly maintained. Identifying these problems early can prevent costly failures, downtime, and safety risks.\nIn this blog, we cover the top 10 common problems in substation isolators and their practical solutions to help engineers and maintenance teams improve system reliability. While our engineers (Isolator experts) visits to substation sites like Jindal Steel works Angul , they found that the existing isolators are heating very much and not having contact alignment of isolator is proper . Such case studies teach our Engineers (Isolator experts) more about ground problems in Isolator switch . We have make summary of points what we observed in case study like JSW steel ltd and many other substation sites. Here we highlighted the points and explained their reason of Isolator problems in substation . \t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
