Description
In this course, you will learn how 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. You will also learn step potential, touch potential, mesh potential, transfer potential, etc which are very important concepts for designing earthing systems. In general overview section, you will learn why do we need earthing and grounding systems and also the three fundamental grounding systems called TN, TT and IT. In measurement section, you will learn how to measure and calculate soil resistivity with different kinds of methods like variation of depth method, Wenner method and Schlumberger-Palmer method. You will also learn how to measure earthing resistance with different kinds of methods namely dead earth method, three point method, fall of potential method and equilateral triangle method. In design section, you will learn different earthing topologies that you can use in your projects and also a comprehensive example about earthing system design is also included in design section. In calculation section, you will learn each calculation method for different earthing system topologies like single earthing rod, single earthing plate, earthing conductor mesh systems without earthing rods, earthing conductor mesh systems with earthing rods, etc.
