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. However, transformer talent is at a premium today, and all aspects of the power industry are suffering a diminishing of the supply of knowledgeable and experienced engineers.Now in print for over 80 years since initial publication in 1925 by Johnson & Phillips Ltd, 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.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 sulphur in oil, geomagnetic induced current (GIC) impacts, transportation issues, 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 LTCs, shunt and series reactors, and HVDC converter transformers. These changes in the thirteenth edition together with updates of IEC reference Standards documentation and inclusion for the first time of IEEE reference Standards, provide recognition that the transformer industry and market is truly global in scale. -- From the foreword by Donald J. FallonMartin Heathcote is a consultant specializing in power transformers, primarily working for utilities.

From the renowned biochemist and author of The Vital Question, an illuminating inquiry into the Krebs cycle and the origins of life. “Nick Lane’s exploration of the building blocks that underlie life’s big fundamental questions—the origin of life itself, aging, and disease—have shaped my thinking since I first came across his work. He is one of my favorite science writers.”—Bill Gates What brings the Earth to life, and our own lives to an end? For decades, biology has been dominated by the study of genetic information. Information is important, but it is only part of what makes us alive. Our inheritance also includes our living metabolic network, a flame passed from generation to generation, right back to the origin of life. In Transformer, biochemist Nick Lane reveals a scientific renaissance that is hiding in plain sight —how the same simple chemistry gives rise to life and causes our demise. Lane is among the vanguard of researchers asking why the Krebs cycle, the “perfect circle” at the heart of metabolism, remains so elusive more than eighty years after its discovery. Transformer is Lane’s voyage, as a biochemist, to find the inner meaning of the Krebs cycle—and its reverse—why it is still spinning at the heart of life and death today. Lane reveals the beautiful, violent world within our cells, where hydrogen atoms are stripped from the carbon skeletons of food and fed to the ravenous beast of oxygen. Yet this same cycle, spinning in reverse, also created the chemical building blocks that enabled the emergence of life on our planet. Now it does both. How can the same pathway create and destroy? What might our study of the Krebs cycle teach us about the mysteries of aging and the hardest problem of all, consciousness? Transformer unites the story of our planet with the story of our cells—what makes us the way we are, and how it connects us to the origin of life. Enlivened by Lane’s talent for distilling and humanizing complex research, Transformer offers an essential read for anyone fascinated by biology’s great mysteries. Life is at root a chemical phenomenon: this is its deep logic.

Transformer, Lou Reed's most enduringly popular album, is described with varying labels: it's often called a glam rock album, a proto-punk album, a commercial breakthrough for Lou Reed, and an album about being gay. And yet, it doesn't neatly fit into any of these descriptors. Buried underneath the radio-friendly exterior lie coded confessions of the subversive, wounded intelligence that gives this album its staying power as a work of art. Here Lou Reed managed to make a fun, accessible rock'n'roll record that is also a troubled meditation on the ambiguities-sexual, musical and otherwise-that defined his public persona and helped make him one of the most fascinating and influential figures in rock history. Through close listening and personal reflections, songwriter Ezra Furman explores Reed's and Transformer's unstable identities, and the secrets the songs challenge us to uncover.
