Abstract

The work presents a brief introduction on existing maintenance types and substations’ componentes and equipments, culminating in a compilation of techniques, tools and standards to prepare and fulfill a 15 kV class substation annual maintenance schedule, based on national and international standards, as well as on the available literature. In order to exemplify the process, a study was carried up on a 1.8 MVA substation, those allocated into 3 separate transformers, beeing two of 750 kVA and one of 300 kVA, seeking out to prepare it’s annual maintenance schedule and perform less invasive tests and inspections.
