Thermal overload tests on a 400-MVA power transformer with a special 2.5-p.u. Short time loading capability.

Thermal overload tests on a 400-MVA power transformer with a special 2.5-p.u. Short time loading capability.

Comprehensive load /thermal testing was performed on a 400/400/125-MVA transformer representing a new design generation for large power transformers with a short time emergency loadability of 2.5 p.u. This particular overloadability factor required special design features to control the very high le...
