Square D Power System Engineering performs time-current coordination analysis with the aid of computer software and the study includes the determination of settings, ratings, or types for the overcurrent protective devices supplied taking into consideration service continuity and system protection goals.

Advantages:

• Log-log plots indicating the degree of system protection and coordination
  • displaying the time-current characteristics of overcurrent devices
    
  • other pertinent system parameters (device descriptions, settings of the adjustable devices, the short-circuit current availability at the device location on the system one-line diagram)
• Tabular computer printout containing suggested device settings
  
  • all adjustable overcurrent protective devices
    
  • equipment where the device is located
    
  • device number corresponding to the device on the system one-line diagram
• Computer generated system one-line diagram clearly identifying
  • individual equipment buses
    
  • bus numbers
    
  • device identification numbers
    
  • maximum available short-circuit current at each bus
• Evaluation of the degree of system protection and service continuity with overcurrent devices
  
• Recommendations for addressing system protection or device coordination deficiencies
