Introduction to Protective Device Coordination Analysis

COURSE NO: E04-030
Introduction to Protective Device Coordination Analysis
Course Highlights

This online engineering PDH course provides an introduction to protective device coordination analysis in a very structured fashion. First, a modelling technique is shown for a generic power system, protective relays are modelled in detail, and relay settings are determined based on short circuit current calculations. A detailed explanation of modelling and calculation procedures is offered. Illustrated techniques can be implemented in any commercial power system software package.


The objective of a protection scheme in a power system is to minimize hazards to personnel and equipment while allowing the least disruption of power service. Coordination studies are required to select or verify the clearing characteristics of devices such as fuses, circuit breakers, and relays used in the protection scheme. These studies are also needed to determine the protective device settings that will provide selective fault isolation. The goal is to achieve an optimum balance between equipment protection and selective fault isolation that is consistent with the operating requirements of the overall power system.


This 4 PDH online course is suitable for electrical engineers with a desire to learn about the analysis of protective device coordination.

Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Understanding the basic theory behind protective device coordination studies
  • Understanding how overcurrent and earth fault protection device coordination is achieved
  • Learning about commercial software modelling techniques, simulation performance and interpretation of the results
