Three winding transformers can also be used in the places
where you have space constraints, there ispite of giving
two no. two winnding transformers one no. three winding
transformer can be used.

A three winding transformer can be can have following
configurations:
A.Configuration-1
1.HV (High Voltage) Winding say 400 kV
2.IV (Intermediate voltage) Winding say 220 kV
3.LV (Low Voltage) Winding say 6.3 kV

B.Configuration-2
1.HV (High Voltage) Winding say 400 kV
2.LV-1 (Low Voltage) Winding say 13.8 kV
3.LV-1 (Low Voltage) Winding say 13.8 kV

With this configuration if we say that MVA capacity of
transformer is 220 MVA (say) at 400 kV, them at 13.8 kV (LV-
1 & LV-2) windings will have MVA capacity of 110 MVA each.

if you are in a software company,then why do you want to come in a core company like sail, ntpc(where lots of trouble like tension but you have a good life in a it company) ?
