Grounding System Theory and Practice

Grounding System Theory and Practice

Author: Velimir Lackovic

The flow of current from an underground-fault condition 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 personnel that may 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 course provides an introduction to grounding system design. It is suitable for electrical engineers with a desire to understand the fundamentals of grounding practices and safety issues related to grounding design. Upon successful completion engineers will be able to address various grounding problems, understand how grounding systems are modelled and how step and touch voltages are calculated.

Once you complete your course review, you need to take a multiple-choice quiz consisting of twennty-five (25) questions to earn 3 PDH credits
