  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.

  Features a new "where are they now" section, with updates about lives of expedition's original climbers and updated resources based on the "Anti-Racism in the Outdoors" (ARITO) guide. 
   
   
   
  Outdoor journalist James Edward Mills's book, The Adventure Gap, is a groundbreaking volume that is equal parts adventure story, history, and inspiration as it chronicles the first American all-Black summit attempt on Denali in 2013. Mills uses this momentous expedition as a jumping-off point to explore diversity in the outdoors, from Mathew Henson who stood at the North Pole in 1909 to contemporary adventurers such as polar explorer Barbara Hillary and rock climber Kai Lightner. 
   
   
   
  This tenth anniversary edition once again shares the compelling events that unfolded during Expedition Denali's summit bid. But it also provides fresh context: A new thought-provoking afterword by Mills examines what has evolved in and around the outdoor community since that effort. He highlights progress and inspiring stories, such as Full Circle Everest, an expedition led by Phillip Henderson that put an all-Black team on top of the world's highest peak. And he points to places where we can and should all strive for higher achievement. The Adventure Gap has become an essential text in outdoor education and inspiration—a story of our times, now more relevant than ever.

  Now a sprawling video game franchise, Resident Evil has kept us on the edge of our seats for decades with its tried-and-true brand of jump scares, zombie action, and biological horror. But even decades after its release, we can't stop revisiting the original's thrills, chills, and sometimes unintentional spills. 
   
    
   
  Pop culture writer and horror cinephile Philip J Reed takes dead aim at 1996's Resident Evil, the game that named and defined the genre we now call "survival horror." While examining Resident Evil's influences from the worlds of film, literature, and video games alike, Reed's love letter to horror examines how the game's groundbreaking design and its atmospheric fixed-cam cinematography work to thrill and terrify players—and why that terror may even be good for you. 
   
   
   
  Featuring a foreword from Troma Entertainment legend Lloyd Kaufman and new interviews with the game's voice actors and its live-action cast, the book serves as the master of unlocking the behind-the-scenes secrets of Resident Evil, and shows how even a game filled with the most laughable dialogue can still scare the pants off of you.

  The Coming Healthcare Revolution identifies and describes five top-down macro forces and five bottom-up market forces that have sufficient strength to transform the US healthcare industry from the outside-in. The powerful macro forces are demographic determinants, funding fatigue, chronic pandemics, technological imperatives, and pro-consumer/market reforms. The equally powerful market forces are whole health, care redesign, care migration, aggregators' advantage, and empowered caregivers. Written by David Johnson and Paul Kusserow, professional healthcare advisors operating at the intersection of healthcare economics, policy, strategy, and capital formation, this book provides expert insight on how the US healthcare system is becoming cheaper, better, more balanced between prevention and treatment, easier to access, and more empowering for both frontline caregivers and consumers. 
   
   
   
  In this book, listeners will learn about factors leading to rising healthcare costs; US healthcare in comparison to other high-income countries; similarities between the US automobile industry crisis in the 1980s and today's adapt-or-die situation for healthcare providers and suppliers; and how the healthcare industry is reorganizing to decentralize delivery of whole-person health in ways that will improve health outcomes and overall societal health.
