J & P Transformer Book

Martin Heathcote07506-1158-8

The J&P Transformer Book, first published in 1925, is known throughout the world as the bible of the power transformer. The twelfth edition is the first revision in fifteen years, and a major re-write, offering more up-to-date and in-depth coverage than any other book.New chapters include: Transformers associated with DC; Phase-shifting Transformers and quadrature boosters; Installation of transformers; Designing an installation.The J & P Transformer Book is the essential reference work for engineers concerned with the design, installation, and maintenance of power transformers. It is also invaluable as a textbook for the architect and system planner as well as for the electrical engineering graduate and student.THE definitive transformer reference book (since 1925!)12th edition is a major re-write and updateMore in-depth coverage than any other competitor”
