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 / satya
the charging current is about 6 times the full load current
about 2000 amps but that will be for mill seconds
