Energy Losses in Electrical Power Systems

Today´s power systems engineer is perplexed by the pressure to ``do something´´ about wasted energy. He needs to know where losses exist in system components, If he can measure them, what are the theoretical savings, and what he can do about them. An Introduction to this continuing subject is given, typical loss data on electrical equipment are provided, and measurement problems are discussed. System design criteria for reducing losses are considered. A checklist for decreasing losses is provided, and operating losses and future savings and trends are discussed.
