  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.

  Estimating isn't difficult when you have a system. The purpose of this book is to help you create that system. It's an approach that helps you estimate without having to think about the process. An orderly approach makes estimating easier and more accurate. 
  Estimating is work, requiring dedication, focus, and practice to get right. It isn't as difficult when you have a system in place. The size of the project might vary but the process doesn't change. This book is about learning the process. 
  This book doesn't guarantee perfect estimates or a profit on your jobs. It's up to you to do the work. By following the principles, the system you develop will improve the ease and accuracy of your estimates, and that will make your company more profitable. 
  Written and narrated by Michael Stone, author of Markup & Profit; A Contractor’s Guide Revisited, a top-selling business management book for the construction industry, and Profitable Sales: A Contractor's Guide, a guide to successfully navigating the world of residential remodeling and specialty sales.

  Death Ray The: The History and...

  Nikola Tesla was one of history’s greatest scientists, and though he is best known for his pioneering work with electricity, the fact that he is mostly remembered solely for that actually does a disservice to his legacy. Born a Serb in the Austrian Empire, Tesla came to the United States and worked in a laboratory for none other than the Wizard of Menlo Park, Thomas Edison. 
  Having established AC as an electrical supply system, Tesla became a global celebrity, and his devices and inventions fascinated people. Tesla tinkered with everything from X-rays to wireless communications and even attempted a primitive form of the radio. While Tesla was not able to successfully execute the devices and concepts he foresaw, his forward thinking in fields like wireless communication certainly proved prescient, and his futuristic devices and his later reputation for eccentricity helped create the “mad scientist” image that still remains a pop culture fixture. Tesla seemed to have come to grips with this aspect of his legacy late in life, noting, “The scientific man does not aim at an immediate result. He does not expect that his advanced ideas will be readily taken up." 
  During World War I, in December 1915, Tesla gave an interview to The New York Times in which he claimed he was working on something entirely new, a weapon that would use electrical power to instantly destroy a distant target. He explained that this weapon was “so far developed that great destructive effects can be produced at any point on the globe, determined beforehand and with great accuracy.” Tesla called this new weapon the “Teleforce,” and he would continue working on this project for the rest of his life, but he consistently refused to give details of its operation. Many people believed it was impractical, but with Tesla, it was never possible to be entirely certain.
