Classification of transformers according to turn ratio:
Slide 7
1- Power transformer 2- Distribution transformer 3- Measuring
transformers A)voltage transformer B) current transformer
4-Autotransformer- Tapped autotransformer Classification of
transformers according to their function:
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.
