Earthing touch potential
WebTherefore, earthing resistance, surface potential and current distribution in the earthing system should be estimated. In addition, the mesh voltage should be below the tolerable touch voltage, or the preliminary design should be modified. Figure 6 shows the potential profile on the substation surface for two types of earthing grid. WebThis 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. …
