Course Description:

This course involves the application of the Power*Tools program to analyze a sample AC electrical distribution system containing various sizes of motors utilizing different starting techniques. A motor starting analysis of the distribution system will be reviewed and then performed using the software. Students will earn 1.6 CEUs for this 2-day course.


Typical Industrial and Commercial Power System Example:

  • Data gathering and input data requirement
  • Exposure to load flow analysis to the extent to establish initial conditions for motor starting analysis
  • Comparison of induction motor models available: single rotor and double rotor circuits vs. graphical model
  • Review of data required to properly model the motor to be started
  • Understanding of the motor performance test data including torque slip vs. slip, current vs. slip, hot and cold start thermal limits, etc.
  • Importance of inertia, both motor and load, on motor starting
  • Discussion of various motor starting methods: delta-wye, autotransformer, capacitor, and soft-start
  • Examination and interpretation of PTW study results and potential problem areas in the power system
  • Discussion of methods and procedures for completing a typical study
  • Overview of motor protection and relationship to motor starting methods
  • Discussion of compliance with various standards and requirements

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

  • Interpretation of Equipment datasheets
  • Data gathering, data input and system modeling
  • Relationship between Load Flow results and Motor Starting study
  • Examination of specific motor starting technique being utilized
  • Verifying compliance with related codes and standards
  • Discussion of study results and methods to improve distribution system

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.
