When charging a 20 MVA , 33kV/6.6kV transformer through
regulated (0-6.6 kV or 0-33 kV) source on no load , what
will be the maximum current drawn by transformer from
source and what sould be the source capacity.
Answer Posted / pulkit
max current when on load wil be 390 amp drawn by the Hv wdg
of t/f and when on no load the transformer primary losses
occur on the basis of elctic flux principle in which when evr
the current flows in a loop,there is loss in the form of
magnetic field energy that is created arround the primary
coil.it is 1 % of the hv wdg current.
