Title: Transformer Engineering Author(s): S.V.Kulkarni & S.A.Khaparde Pages: 478 Publisher: Marcel Decker Publication date: 2004 Language: English Format: PDF ISBN-10: 0824756533 ISBN-13: Description: In the last decade, rapid advancements and developments have taken place in the
design, analysis, manufacturing and condition-monitoring technologies of
transformers. The technological progress will continue in the forthcoming years.
The phenomenal growth of power systems has put tremendous responsibilities on
the transformer industry to supply reliable and cost-effective transformers.
There is a continuous increase in ratings of generator transformers and
autotransformers. Further, the ongoing trend to go for higher system voltages for
transmission increases the voltage rating of transformers. The increase in current
and voltage ratings calls for special design and manufacturing considerations.
Advanced computational techniques have to be used that should be backed up by
experimental verification to ensure quality of design and manufacturing
processes. Some of the vital design challenges are: stray loss control, accurate
prediction of winding hot spots, short-circuit withstand capability and reliable
insulation design. With the increase in MVA ratings, the weight and size of large
transformers approach or exceed transport and manufacturing capability limits.
