As the first of The Relay Testing Handbook series, this package contains the fundamentals of electrical theory that should be understood by all relay testers. This information will provide a foundation that all future publications will use when describing the most common protective elements, how they function, and the most comprehensive and efficient testing procedures used for testing. Topics covered in this package include:

• How generators create electricity
  
• Phasor diagrams
  
• Three-phase connections
  
• Watts, VARs, VA and the power triangle
  
• Inductive and capacitive VARs
  
• Power transformer’s fundamentals and calculations
  
• Current Transformers (CTs)
  
• Potential or Voltage Transformers (PTs/VTs)
  
• Methods of system grounding with calculations
  
• Positive, negative, and zero sequence components
  
• An introduction to protective relays
  
• Zones of protection
  
• Fault Studies
  
• Protective relay coordination
