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
Bhel,
2168Why generally the Rating of Transformers are in additions of 11 i.e. 11 kVA, 22 kVa, 33 kVA, etc........
8 15903i have three phase 25kva transformer but there is two phase line how can i connect to the two phase line?
2 6018we have 3 single phase transformers. how will we generate 6 supply from 3 phase supply input
NHPC,
2120why transformer cannot rotate though the princplebehind induction motor is similar to a transformer?
