Preface to The J and P Transformer Book

The design and manufacture of transformers is not cutting-edge technology and compared with many fi elds of engineering, progress is slow and change is gradual.

The question might therefore be asked as to what is the need for a new and revised edition of The J & P Transformer Book.

It is also true that in many branches of the industry the book has become well known and widely respected, and many owners will not consider replacing their trusted old edition. Indeed, many transformer engineers swear by copies handed down to them from older colleagues.

After all, transformers are expected to have long lives so that many that are currently in service could have been designed 20 or 30 years ago using practices that have long been considered out of date. True, but the industry does change and the Twelfth edition certainly did appear at a time of great change.

Electricity supply privatization in the UK was beginning to have a significant impact on procurement strategy; the single European market was becoming well established, and its effects strongly felt.

There have been many mergers in the industry; many well known and well-respected manufacturers in Europe and the USA have disappeared.

The result is that the industry has become truly an international one, national standards are disappearing and international standards, in particular those of the IEC, are becoming dominant.

The Twelfth Edition of J & P, as it has tended to become known, certainly introduced change; it was the first to have been written by an author who was not primarily a manufacturer. The impression is that the change has been appreciated by readers.

The Twelfth edition was, however, written from a UK viewpoint, and with UK experience and practices in mind. This Thirteenth Edition has aimed to be less parochial and recognize that, practices may differ in different parts of the world; that there is often more than one way of resolving a problem;

and the way that is familiar might not necessarily be the only way. That view has been acknowledged primarily by reducing the references to British Standards with which a high proportion of readers will not be familiar and replacing these with European and International Standards.

It is clear that these industry changes can and will go further so that there will undoubtedly be a need for further revision to this work in the not so distant future, but it is hoped that the changes introduced in this edition will prove helpful, will not disappoint readers, and neither will they detract from the appeal of The J & P Transformer Book to a wide international readership.

The J & P Transformer Book continues to withstand the test of time as a key body of reference material for students, teachers, and all whose careers are involved in the engineering processes associated with power delivery, and particularly with transformer design, manufacture, testing, procurement, application, operation, maintenance, condition assessment, and life extension.

As a measure of its popular and wide-scale appeal, an internet search on the title results in over 15,000 reference hits from a large number of countries and in multiple languages.

Now in print for over 80 years since initial publication in 1925 by Johnson & Phillips Ltd., the text has grown and changed over time from its original intent as a guide for transformer theory, design, and construction from a manufacturing perspective, and continues to steadily expand on the incorporation of the information needed for a user to apply transformer equipment knowledgeably and effectively.

Evolutions in transformer experience, knowledge, design calculation capability, manufacturing process, MVA and voltage ratings, and application needs, together with the understanding of new problems and development of new solutions have all been reflected as this book has been revised and updated.

Current experience and knowledge have been brought into this thirteenth edition with discussions on moisture equilibrium in the insulation system, vegetable-based natural ester insulating fluids, industry concerns with corrosive sulfur in oil,

geomagnetic induced current (GIC) impacts, transportation issues, a new emphasis on measurement of load-related noise, and enhanced treatment of dielectric testing (including Frequency Response Analysis), Dissolved Gas Analysis (DGA) techniques and tools, vacuum LTC’s, shunt and series reactors, and HVDC converter transformers.

The historical basis of the book continues to highlight British experience, but these changes in the thirteenth edition together with updates of IEC reference Standards documentation and inclusion for the fi rst time of IEEE reference Standards, provide a more universal flavor to the volume and a recognition that the transformer industry and market are truly global in scale.

The book was last updated in 1998 by Martin J. Heathcote, and in preparing this edition, Mr. Heathcote has continued to draw on his contacts and experience in both the manufacturing and user arenas to provide relevance and value to the industry.

Upon graduating from the University of Sheffi eld in Electrical Power Engineering, his career began immediately with the Transformer Division of Ferranti Limited, where his training led to a position as a transformer designer.

After successfully working on designs up to 400 kV, Mr. Heathcote moved from manufacturing to the other side of the aisle and worked for over 20 years on various power engineering projects for the Central Electricity Generating Board (CEGB) in the UK, culminating in a role as CEGB Generating Division’s Transformer Engineer.

Subsequently, since 1992 he has provided consulting services specializing in power transformers, primarily working for utilities.

In this context, he has established working relationships with transformer manufacturers on several continents.

Transformer talent is at a premium today, and all aspects of the power industry are suffering a diminishing supply of knowledgeable and experienced engineers.

Manufacturers still retain highly capable transformer expertise, but their depth of engineering manpower resources is sometimes reduced – perhaps mistakenly – by market economics.

Utilities have difficulty retaining young engineers in the fi eld long enough to develop expert status, and in many cases, transformer engineering is outsourced.

From my perspective, maintaining appropriate power systems and equipment expertise is necessary for a utility to support the reliability, availability, and quality of service goals demanded by energy consumers now and into the future.

As a result, there is a drive in the industry to capture knowledge and experience before it is lost. While familiar with the stature of the book when Mr. Heathcote asked me to consider this Foreword, it was not until I reviewed through this edition that I learned the enduring value of the J&P Transformer Book as a thorough and vital collection of transformer learning to facilitate that continuing education.

In a single volume, it brings back to mind much of the experience and knowledge I had been exposed to in over 25 years working for a major US utility with technical responsibility for the health and well-being of an fl eet of over 1000 power transformers, and in participating during that same period in the standards development and maintenance work of the IEEE/PES Transformers Committee, a group for which I am privileged to presently serve as Chair.

The J&P Transformer Book has served well to educate prior and present generations, and this thirteenth edition continues to be a steady reference to those in the industry and a source of new knowledge to future students and engineers.

I will enjoy reviewing it often as my career in this interesting field continues, and I trust you will find it a useful addition to your technical library
