Substation Grounding & EPR Design using CDEGS

Master the principles of substation grounding and Earth Potential Rise (EPR) design using CDEGS. Learn how to analyze soil resistivity, model grounding grids, and ensure compliance with safety standards to protect both equipment and personnel.

We maximize practical skills for future-ready engineers

Foundation

Understand the fundamentals of substation grounding, soil resistivity, and safety concepts essential for reliable power system design.

Analysis

Learn to evaluate grounding systems and calculate Earth Potential Rise (EPR) using industry-standard methodologies.

Design

Build efficient grounding grid models using CDEGS, ensuring compliance with IEEE standards and real-world project requirements.

Application

Apply your knowledge through case studies, simulations, and practical scenarios used in modern substation projects.

Why Substation Grounding & EPR Design Matters

In power system studies, the accuracy of grounding design directly impacts safety, equipment protection, and regulatory compliance. Poor grounding and incorrect EPR estimation can lead to:

Unsafe touch and step voltages
Risk of electric shock hazards
Equipment damage due to improper fault current dissipation
Non-compliance with IEEE and international safety standards

This program focuses on practical implementation of substation grounding design using CDEGS, helping you understand soil modelling, grid design, and accurate EPR analysis for real-world applications.
