Power Transformers And Special Transformers

Power Transformers And Special Transformers by S. Rao

---

Book Summary:

Since the publication of the first edition in 1985, many advances have occured in Transformers Technology. EHV-AC and UHV-AC transmission systems have been introduced. Installed capacities have increased. Interconnections have been added. The demands made by power systems on Power Transformers, Shunt Reactors, Special Transformers etc. have diversified. Power Transformer, Shunt Reactor and Special Transformer Technologies have kept pace with these pressing demands.

The annual growth rate of distribution transformer and power transformer industry is more than 18 per cent. The total installed capacity of power transformers in India is likely to cross, 15,00,000 MVA by the year 2015 AD.
