A grounding system typically consists of a grounding conductor, a bonding connector, its grounding electrode (typically a rod or grid system), and the soil in contact with the electrode.Why is a grounding configuration important?Abstract: The selection of a grounding configuration and design of a grounding impedance is of vital importance for the stability and functionality of power systems, including industrial and commercial power systems. These key aspects of grounding systems have been the subject of various standards, industrial codes, and recommended practices.
What are the different types of system grounding?System grounding falls into 3 general catego-ries: solidly grounded, ungrounded, or resistance grounded, with there being diferent subcategories of resistance grounding. It is acknowledged that there are other types of grounding methods beyond these 3, but they are rare and beyond the scope of this document.
Why are different grounding system designs used for power systems?The various grounding system designs are implemented for power systems components in order to assess their capabilities and performance. Several tests are conducted for ground faults, when different grounding system designs are used.
What is a resistance grounded system?In a resistance grounded system, a resistor is inserted between the neutral point and ground. Depending on the value of the resistor, the grounding can either be considered low-resistance grounding or high-resistance grounding. Figure 3. Resistance Grounded System.
What are the design criteria for substation earthing systems?Before the 1960s the design criterion of substation grounding or earthing systems was “low-earth resistance.” (Earth Resistance< 0.5 ohms for High Voltage installations). During 1960s, the new criteria for the design and evaluation of substation earthing system were evolved particularly for EHV AC and HVDC Substations. The new criteria are:.
