  • Slide 8
  • It is a power transformer connected to the output of a generator and used to step its voltage up to the transmission level. Power Transformer A 1300 MVA, 24.5/345 kV, 60Hz transformer with forced oil and air (fan) cooling.
  • Slide 9
  • It is a transformer converting the distribution voltage down to the final level. Distribution Transformer A 60 MVA, 225/26.4 kV, 60 Hz transformer showing the conservator.
