- 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.
- Slide 10
- Classification of transformers according to number of phases: 1- Single phase transformer 2- Poly phase transformer
