201 Power Systems Application Training

Protection & Coordination

 
 
     
 

Objectives:

  • Review of fundamental considerations for protection, including data gathering, fault calculations, equipment damage and safety
  • Review of fault calculations and protective device evaluation
  • Overview of protection of apparatus including conductors, transformers, motors and generators
  • Coordination of Overcurrent Protection Devices
  • Discuss compliance with various codes and standards including ANSI, NEMA, NEC® and CEC
  • Provide practical examples of overcurrent coordination, including the understanding of protection versus coordination and continuity of service for both phase and ground overcurrent
  • Presentation of several class examples that will help students gain a basic understanding of how to select and apply conductors, fuses, low and medium voltage circuit breakers, overcurrent relays and current transformers
  • Discuss issues and examine study results, potential problem areas and implementation of study recommendations

Prerequisites:

  • Basic computer skills
  • SKM Power*Tools Standard 3-Day and Advanced 2-Day Training OR working knowledge of SKM PTW Software
    This class is not recommended for beginners.
  • Students are urged to review:
    • IEEE Red Book Std 141-1993, chapter 4, 5, 10
    • IEEE Buff Book Std 242-2001, chapters 9, 10, 11, 12, 15

Course Description:

The course involves the application of the Power*Tools program to analyze a sample electrical distribution system. This training program explains the rules and techniques of coordinating protective relays, power fuses and circuit breakers. Practical exercises of distribution system protection and coordination will be reviewed and then performed using the software.

When preparing arc flash analysis, it is vitally important to perform accurate short circuit, protection and coordination studies. This course will provide the background and understanding required to perform these studies. Students will earn 2.0 CEUs for this 3-day course.

 
 

Typical Industrial and Commercial Power System Example:

  • Review of distribution system analysis topics including short-circuit, protection of apparatus, protective device coordination, and equipment evaluation
  • Discussion of compliance with various standards and requirements
  • Data gathering and input data requirement
  • Discussion of considerations when selecting equipment
  • Output data requirement
  • Examination and interpretation of PTW study results and potential problem areas in the power system
  • Discussion of equipment evaluation and coordination study results
  • Discussion of methods and procedures on completing a typical study
  • Discussion of coordination study results
  • Discussion of final presentation of study reports

Hands-On Lab - Analysis of a Sample Electrical Distribution System in PTW:

  • Design a new power system and analyze an existing system with expert guidance.
  • Proper equipment selection for coordination and evaluation of the design - why certain devices should be used instead of others
  • Apparatus Protection - Transformers, Conductors, and Overload conditions
  • Discussion of common coordination issues, errors, and misconceptions. Rules of thumb to quickly spot uncoordinated systems
  • Develop guidelines to clarify possible coordination confusions
  • Interpretation of Equipment datasheets
  • Relationship between Short Circuit results and Protective Device Coordination study
  • Discussion of study results and methods to improve system protection and coordination
  • Discussion of issues related to Selective Coordination and compliance with related codes and standards
   
   
 
 

Target Audience:

This course is intended for electric power engineers responsible for the design and analysis of three phase electrical distribution systems. No previous electrical distribution system analysis experience is required. However, it is HIGHLY recommended that courses 101 and 102 have been previously completed or have several years of PTW experience.

SKM will provide the latest version of the PTW software prior to the class for installation. License key will be provided the week before the course.
Course Locations Web-Based Live Training - This online training will be conducted live by a senior SKM engineer and other SKM engineers will be available via chat or phone to assist with questions.  The same level of instruction, content, and practice projects will still be covered as we normally do. Software activation details will be provided as we get closer to the class.  A hardcopy training manual will be shipped about 10 days before the first day of class. Student within the continental US qualify for free shipping (UPS) of the hardcopy student manual. Students outside of the US are responsible for delivery fees and duties and/or customs fees.

Live online training will be conducted using the GoToTraining platform. We recommend using a Chrome browser for the instant join feature without having to download and install extra software. Consider a dual-monitor setup so that you can view the instructor’s screen while performing hands-on exercises. Alternatively, you can join the meeting on a tablet using GoToTraining’s app or use another computer next to you.
