Earthing and Grounding in Power Systems: Calculations, Design and Measurements

Learn to calculate, design and measure earthing and grounding systems. This course covers all of the earthing issues that you can deal with in real-life applications. 27 lectures in 4h 36m total course length.

Course Description

This course will teach you how to calculate, design, and measure earthing and grounding systems. It covers all of the earthing issues you can deal with in real-life applications. You will also learn step potential, touch potential, mesh potential, transfer potential, etc., which are fundamental concepts for designing earthing systems.

In the General Overview section, you will learn why we need earthing and grounding systems and the essentials of TN, TT, and IT grounding systems.

In the Measurement section, you will learn how to measure and calculate soil resistivity with different methods like the variation of depth method, Wenner method, and Schlumberger–Palmer method.

You will also learn how to measure earthing resistance using the following methods: The dead earth method, the Three-point method, the Fall of the potential method, and the Equilateral triangle method.

In the Design section, you will learn various earthing topologies that you can use in your projects. A comprehensive example of the earthing system design is included in the Design section.

In the Calculation section, you will learn each calculation method for different earthing system topologies like a single earthing rod, single earthing plate, earthing conductor mesh systems without earthing rods, earthing conductor mesh systems with earthing rods, etc.
