1Rising Acetylene in a 10 MVA Distribution Transformer: De-rate, Monitor or Withdraw?
A 10 MVA, 33/11 kV, Dyn11 distribution transformer commissioned in 2009 supplies an industrial feeder. Peak demand has grown from 6.5 MW to 8.6 MW at 0.90 power factor, so the unit runs near nameplate for about five hours every evening.
