  Introduction to Power System...

  Power system protection systems have three basic components: Instrument transformers, Relays, Circuit breakers
  
  The function of the CT is to reproduce in its secondary winding a current I' that is proportional to the primary current I. The CT converts primary currents in the kiloamp range to secondary currents in the 0–5 ampere range for convenience of measurement.
  
  The function of the relay is to discriminate between normal operation and fault conditions. The OC relay in Figure 2 has an operating coil, which is connected to the CT secondary winding, and a set of contacts. When |I'| exceeds a specified ''pickup'' value, the operating coil causes the normally open contacts to close. When the relay contacts close, the trip coil of the circuit breaker is energized, which then causes the circuit breaker to open.
  
  System-protection components have the following design criteria:
  • Reliability: Operate dependably when fault conditions occur, even after remaining idle for months or years. Failure to do so may result in costly damages.
  • Selectivity: Avoid unnecessary, false trips.
  • Speed: Operate rapidly to minimize fault duration and equipment damage. Any intentional time delays should be precise.
  • Economy: Provide maximum protection at minimum cost.
  • Simplicity: Minimize protection equipment and circuitry.
  
  Since it is impossible to satisfy all these criteria simultaneously, compromises must be made in system protection.
  
  The book consists from the following sections:
  1. Chapter 1: Power System Faults:
  2. Chapter 2: Instrument Transformers.
  3. Chapter 3: Overcurrent and Earth Fault Protection Relays.
  4. Chapter 4: Radial System Protection.
  5. Chapter 5: Zones of Protection.
  6. Chapter 6: Differential Relays.
  7. Chapter 7: Distance Relays.
  8. Chapter 8: Transformer Protection.
  9. Chapter 9: Generator Protection.
  10. Chapter 10: Busbar Protection.
  11. Chapter 11: Circuit Breakers.
  12. Chapter 12: Fuses.
  13. Chapter 13: References.

  Finding Genius: Understanding...

  This book is for three kinds of audiences: 1) curious amateurs interested in science or overall wellness, 2) anyone who has been diagnosed with cancer or knows someone who has, and 3) medical, bioengineering, or other professionals who have a general knowledge of and curiosity about any or all aspects of cancer biology and treatment, but who are not experts in the field. 
  This book is the result of 70+ interviews of genius-level medical and science professionals, primarily in cancer biology, research, and medicine. They have all been asked the same set of questions, and have answered to the best of their ability and knowledge. 
  What you’re about to read is the answers to these questions, not from all the individuals, but from the most interesting 4 to 9 who answered each question. 
  At the start of my journey in science, I already had a B.S. in Chemical Engineering, but that was from 1998, certainly not 2016 when I started. Reading scientific papers was difficult at first – I understood about 10% of what I was reading. As I interviewed more scientists, researchers, clinicians and others, I started to pick up the vocabulary and thinking process needed to read scientific papers. 
  After a year of reading, my comprehension increased, and now stands at around 70%, typically. In the areas of physics or other sciences in which I’m not conversant, I understand about 30%. In advanced math, since it’s a language unto itself, especially at high levels, I am back to the 10% level. Apply yourself, and you’ll be surprised by what you can learn in a year’s time.

  “Tells the story of anger, disillusionment, and determination of Americans to develop a political movement to fight chemical pollution . . . timely.” —The Huffington PostThis book, named one of Booklist’s Top 10 books on sustainability in 2014, is the first to offer a comprehensive examination of the environmental health movement, which unlike many parts of the environmental movement, focuses on ways toxic chemicals and other hazardous agents in the environment effect human health and well-being. Born in 1978 when Lois Gibbs organized her neighbors to protest the health effects of a toxic waste dump in Love Canal, New York, the movement has spread across the United States and throughout the world. By placing human health at the center of its environmental argument, this movement has achieved many victories in community mobilization and legislative reform. In The Rise of the U.S. Environmental Health Movement, environmental health expert Kate Davies describes the movement’s historical, ideological, and cultural roots and analyzes its strategies and successes.“Kate Davies’ excellent book focuses on the role of health in the environmental health movement and encourages us to consider its origins and accomplishments . . . The Rise of the U.S. Environmental Health Movement looks both back and forward to challenge us to consider our current direction. In the future this book will provide readers with an important perspective on how the environmental health movement shaped our society.” —Toxipedia“A well-done history of America’s environmental health movement . . . offers readers valuable information on how grassroots organizing prevents harm from toxic exposures and leads to safe and healthy communities.” —Lois Marie Gibbs, Executive Director, Center for Health, Environment & Justice

  Matter - The Magnificent Illusion

  Guido Tonelli

  • 0

  What are we made up of? What holds material bodies together? Is there a difference between terrestrial matter and celestial matter? When Democritus stated that we are made up of atoms, few people believed him. Not until Galileo and Newton in the seventeenth century did people take the idea seriously, and it was another four hundred years before we could reconstruct the elementary components of matter. 
   
   
   
  Everything around us has very particular properties. These properties, which seem quite normal to us, are in fact very special, because the universe, whose evolution began almost fourteen billion years ago, is today a very cold environment. In this book, Guido Tonelli explains how elementary particles, which make up matter, combine into bizarre shapes to form correlated quantum states, primordial soups of quarks and gluons, or massive neutron stars. New questions that have emerged from the most recent research are answered: in what sense is the vacuum a material state? Why can space-time also vibrate and oscillate? Can elementary grains of space and time exist? What forms does matter assume inside large black holes? 
   
   
   
  In clear and lively prose, Tonelli takes listeners on an exhilarating journey into the latest discoveries of contemporary science, enabling them to see the universe, and themselves, in a new light.
