I am designing new project sub station with 220 kV / 11 kV,
40 MVA capacity. This project have many recifier sets,
which can generate 3rd harmonics. Now I have to select
vector group of This transformer. To minimise 3rd
harmonics, what care should I take in selection of
Transformer Vecrtor group? If it is Y-Y with open Delta
tertiary then what should be the rating & voltage of
What are the KPI that decides the capacity expansion of
