i think that generators at generation stations are max:
design for the voltage level 11 kv, beyond this design
matter like insulation matters. that 11 kv is step up 3,11
or more time

should %impedance be high or low in a power transformer? if so why?

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
