Three-phase oil-immersed distribution transformers 50 Hz, from 50 kVA to 2500 kVA with highest voltage for equipment not exceeding 36 kV - Requirements and tests concerning pressurised corrugated tanks Ingestion-build-264231 and other printing processes have1 Scope This Part 4 of EN 50464 series is applicable to test procedures to verify the mechanical withstand capability of the corrugated tanks of completely oil filled and hermetically sealed distribution transformers. NOTE Variations of oil temperature due to variations of ambient temperature and loading, result in deformation of tank walls.
