An earthing system (UK and IEC) or grounding system (US) connects specific parts of an electric power system with the ground, typically the equipments conductive surface, for safety and functional … See more

In low-voltage networks, which distribute the electric power to the widest class of end users, the main concern for design of earthing systems is safety of consumers who use the electric … See more

According to the IEEE standards, grounding rods are made from material such as copper and steel. For choosing a grounding rod there are several selection criteria such as: corrosion resistance, diameter depending on the fault current, conductivity and … See more

Soil resistance is a major aspect in the design and calculation of an earthing system/grounding installation. Its resistance … See more

There are three main purposes for earthing:
System earthing
System earthing serves a purpose of electrical safety throughout the system that is not caused by a short circuit or other See more

In high-voltage networks (above 1 kV), which are far less accessible to the general public, the focus of earthing system design is less on safety and more on reliability of supply, reliability of protection, and impact on the equipment in presence of a short … See more
