Use this Substation Maintenance Inspection Checklist to conduct a detailed investigation of each substation's equipment. Maintain a record of the most current readings and observations to ensure that all parts, from the main transformer, cooling/heating systems, bushings, and tap changer tanks, to every switch and connection, comply with industry regular standards. Identify any electrical issues before they lead to serious problems and schedule corrective maintenance activities as needed. Customize this form to accommodate both quantitative and qualitative assessment of the substations and avoid heavy repair costs in the long run. This form will work in areas with or without an internet connection.
