In the newest edition, the reader will learn the basics of transformer design, starting from fundamental principles and ending with advanced model simulations. The electrical, mechanical, and thermal considerations that go into the design of a transformer are discussed with useful design formulas, which are used to ensure that the transformer will operate without overheating and survive various stressful events, such as a lightning strike or a short circuit event. This new edition includes a section on how to correct the linear impedance boundary method for non-linear materials and a simpler method to calculate temperatures and flows in windings with directed flow cooling, using graph theory. It also includes a chapter on optimization with practical suggestions on achieving the lowest cost design with constraints.
Presents new developments, including losses in tank walls, simpler directed flow cooling calculations using graph theory, and a two core circuit model.
Covers nonlinear constrained optimization theory applied to achieving a low cost transformer, which satisfies various constraints.
Includes new chapters and sections.
Begins with fundamental principles and builds to advanced model simulations.
Utilizes more mathematical details than traditional books on transformers.
