Generally, the construction of power transformers for transformers rated a few kVA up to several hundred MVA is according to similar principles [].Also, manufacturing the larger size transformers need much experience and sophistication [1,2,3,4,5,6]; therefore, most manufacturers divide the production into two categories i. distribution transformers (up to 2500 …
Elektriske tog har et stort men kort effektforbrug, hvilket er problematisk for el-nettet. Vi vil anvende et 3.3 MW magnetisk svinghjul som energilagring, til at belaste el-nettet med en jævn, men lille belastning, som så kan levers til togene, når dette er påkrævet. Svinghjulet vil blive testet på en togtransformerstation i Nordsjælland
