Basic Tools for Electrical Protection and Short Circuit
Course Highlights

This online engineering PDH course presents the basic principles of the physics of overcurrents and their effects in electrical components. It discusses overcurrents of fault magnitude including basic methodology for the calculation of short circuits, which can be used as a basis for software calculations.


This course also describes symmetrical components for the engineer to have a basic knowledge of the mathematics of short circuit calculations. It presents per unit calculations method and examples, including conversion from one base to another, to analyze a power system using single line diagrams.


Overcurrent phenomena are complex events. When a circuit changes from a steady state condition to a completely different electrical state, the electrical components react in different ways. Analysis of these changing conditions, its physics and mathematical interpretation, are all part of the tasks that an engineer must tackle in order to understand how to protect the circuits, and in many cases, the personnel who work around the electrical system.


The 4 PDH online course is intended for electrical, chemical and mechanical engineers, as well as project managers in industry, who are interested either in learning more about electrical protection and the basis of short circuit methodology, or wish to refresh electrical protection and elements of the mathematics behind short circuit calculation concepts.
