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 / dinesh lokhande
Actually above answer is not correct as it is the full load
current.No load current is approximately 4 to 5 % of rated
full load current. hence considering the terminals (i.e HV
side or LV side) the current drawn from source will be 4 to
5 % of respective side rated current.
