Oil power transformers are typically installed at transmission and distribution substations, generating stations as generator step up units, industrial plants with high power demand, and outdoor grid nodes. They are placed on foundations with containment pits and fire safety provisions. In utility networks, they often sit in switchyards, fenced substations, and outdoor pad mounted enclosures depending on voltage class. Location choice is driven by clearance requirements, access for maintenance, cooling airflow, and environmental containment rules.
