Dear sir, In our plant have Station Transformer having
capacity,i want to know, why LV side 40 - 40MVA is given?
& how we can get 6.3 KV supply from tertiary(i.e. Open
delta connection), Vector Group YNyn0 - yn0 +d
MVA Rating 80MVA / 40 - 40MVA + 26.7MVA Voltage rating 420
(Tap range +6,to -10)81.25% /11.5KV - 11.5KV +6.3KV
