Each company forming ABB has performed a large number of short circuit tests forming the basis for its design standards
The “Merger-projects” evaluated the different Power Transformer technologies and standards
In each area; Buckling, Tension, Compression, Tilting, etc the various standards were compared against actual test results.
The standards and principles that were found most relevant and safe were adopted
A new ABB Technical Standard was issued containing the agreed “best practices”
This Standard is adopted worldwide in the TrafoStarTM concept
The TrafoStar concept has been proven by 49 full scale tests since 97
The Standard is continuously improved as a result of new findings
