Learn how to ensure optimal efficiency! Save money, resources -- and downtime -- with this invaluable reference that can help you evaluate and improve transformer efficiency in electric power systems more reliably. The author, a professional electric system efficiency expert, clearly explains the typical causes of poor efficiency in transformer-load and no-load losses. He reviews traditional efficiency improvement methods, such as the use of larger conductors and properly sizing transformers, as well as effective new solutions, including the use of amorphous steel and cryogenics, laser-etched silicon steel, and advanced design transformers. This is relevant, ready-to-use information that should be interest to any cost-conscious commercial and industrial engineer manager.
