**课程名称：** 电力工程 第三章：接地与接地系统 **课程概述：** 本课程将教授如何计算、设计和测量接地与接地系统。课程内容涵盖了实际应用中可能遇到的所有接地问题。您将学习到对接地系统设计至关重要的概念，如跨步电压、接触电压、网格电压和转移电压等。 在整体概述部分，您将了解接地和接地系统的必要性，以及三种基本的接地系统：TN、TT 和 IT。 在测量部分，您将学习如何使用不同的方法测量和计算土壤电阻率，包括深度变化法、温纳法和舒勒-帕尔默法。此外，您还将学习如何使用多种方法测量接地电阻，例如假接地法、三点法、电位降法和等边三角形法。 在设计部分，您将了解可用于项目的不同接地拓扑结构，并附有一个关于接地系统设计的综合示例。 在计算部分，您将学习不同接地系统拓扑结构（如单接地极、单接地极板、无接地极的接地导体网格系统、带接地极的接地导体网格系统等）的各种计算方法。
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.
