Grounding System Theory and Practice
This online engineering PDH course provides an introduction to grounding system design. It addresses various grounding problems, describes how grounding systems are modelled and explains how step and touch voltages are calculated.
In underground-fault conditions, the flow of current will result in voltage gradients within and around the substation, not only between structures and nearby earth, but also along the ground surface. In a properly designed system, this gradient should not exceed the limits that can be tolerated by the human body.
The purpose of a ground mat study is to provide for the safety and well-being of anyone that can be exposed to the potential differences that can exist in a station during a severe fault. The general requirements for industrial power system grounding are similar to those of utility systems under similar service conditions. The differences arise from the specific requirements of the manufacturing or process operations.
This 4 PDH online course is applicable to electrical engineers with a desire to understand the fundamentals of grounding practices and safety issues related to grounding design.
This PE continuing education course is intended to provide you with the following specific knowledge and skills:
Understanding the basic theory behind grounding system analysis
Understanding why grounding systems are important part of commercial and industrial power systems
Learning how to calculate step and touch voltages
Understanding the consequences of inadequate grounding system design
Learning about commercial software modelling techniques, simulation performance and interpretation of the results
