What is Earthing Design and Why is it Important?




Earthing design, also known as grounding design, is the process of designing an earthing system that connects an electrical power system with the earth's conductive surface, for both safety and functional purposes. An earthing system consists of various components, such as conductors, rods, electrodes, grids, mats, plates, wires, cables, connectors, etc., that provide a low-resistance path for fault currents to flow into the ground.


The main purpose of earthing design is to ensure the safety of people and equipment from electric shock hazards, such as touch and step voltages, that may arise during fault conditions or lightning strikes. Earthing design also helps to improve the electromagnetic compatibility of an installation, by reducing interference, noise, harmonics, transients, etc., that may affect the performance and reliability of electrical devices. Furthermore, earthing design can also provide functional benefits, such as voltage stabilization, power quality improvement, signal reference, etc.


Earthing design is a complex and challenging task that requires a careful and systematic approach. It involves many factors and parameters that need to be considered, such as soil resistivity, fault current level, grid configuration, conductor size and type, safety criteria, etc. It also requires compliance with various standards and regulations that govern the requirements and specifications for earthing design. Some of the most common standards and regulations for earthing design are:


  • IEC/TS 60479: Effects of current on human beings and livestock



  • EN 50522: Earthing of power installations exceeding 1 kV AC



  • IEEE Standard 80: Guide for safety in AC substation grounding



  • IEC 62305: Protection against lightning



How to Perform Earthing Design Using Software?




To perform earthing design using software, you need to follow some steps and methods that will help you to achieve a safe and optimal solution. Here are some of the common steps and methods for earthing design using software:



  • Measure the soil resistivity of the site using a suitable method, such as the Wenner or Schlumberger method. Soil resistivity is a key parameter that affects the resistance and potential distribution of the earthing system. It can vary depending on the soil type, moisture, temperature, depth, etc. You can use software tools, such as RES2DINV or RES3DINV, to perform soil resistivity measurements and analysis .



  • Determine the fault current level and duration that the earthing system needs to withstand. Fault current is the maximum current that flows through the earthing system during a fault condition, such as a short circuit or a lightning strike. It depends on the source impedance, load impedance, fault impedance, etc. You can use software tools, such as ETAP or SKM PowerTools, to perform fault current calculations and analysis .



  • Design the grid configuration and layout of the earthing system using a suitable method, such as the mesh or radial method. Grid configuration and layout are important factors that affect the resistance and potential distribution of the earthing system. They depend on the available space, soil conditions, existing structures, etc. You can use software tools, such as CDEGS or XGSLab, to perform grid configuration and layout design and analysis .



  • Select the conductor size and type for the earthing system using a suitable method, such as the circular mil or cross-sectional area method. Conductor size and type are important factors that affect the resistance and potential distribution of the earthing system. They depend on the fault current level, duration, temperature rise, material properties, etc. You can use software tools, such as EDSA or CYME GRD, to perform conductor size and type selection and analysis .



  • Calculate the touch and step voltages for the earthing system using a suitable method, such as the IEEE 80 or EN 50522 method. Touch and step voltages are the voltages that a person may experience when touching an energized object or stepping on the ground near an earthing system during a fault condition. They are the main criteria for assessing the safety of an earthing system. You can use software tools, such as WinIGS or GroundMat, to perform touch and step voltage calculations and analysis .



  • Optimize the earthing system design using a suitable method, such as the genetic algorithm or particle swarm optimization method. Optimization is the process of finding the best solution for an earthing system design that meets the safety criteria and minimizes the cost and material usage. You can use software tools, such as MATLAB or Python, to perform optimization methods and analysis .

FAQs




Q1: What is the difference between earthing and grounding?




A1: Earthing and grounding are often used interchangeably, but they have some differences in meaning and application. Earthing refers to the connection of an electrical power system with the earth's conductive surface, for both safety and functional purposes. Grounding refers to the connection of an electrical device or circuit with a common reference point, such as the earth or a neutral conductor, for both safety and functional purposes. Earthing is usually done at the source or substation level, while grounding is usually done at the device or circuit level.


Q2: How to measure soil resistivity for earthing design?




A2: Soil resistivity is a key parameter that affects the resistance and potential distribution of the earthing system. It can be measured using various methods, such as the Wenner or Schlumberger method. These methods involve driving four electrodes into the ground at equal distances, and applying a known current between the outer electrodes, while measuring the voltage between the inner electrodes. The soil resistivity can then be calculated using a formula that depends on the electrode spacing and arrangement. Soil resistivity can also be measured using software tools, such as RES2DINV or RES3DINV, that perform soil resistivity measurements and analysis.


Q3: How to calculate touch and step voltages for earthing design?




A3: Touch and step voltages are the voltages that a person may experience when touching an energized object or stepping on the ground near an earthing system during a fault condition. They are the main criteria for assessing the safety of an earthing system. They can be calculated using various methods, such as the IEEE 80 or EN 50522 method. These methods involve applying a fault current to the earthing system, and calculating the potential distribution on the surface of the ground and on the energized objects. The touch and step voltages can then be calculated using formulas that depend on the potential difference, body resistance, contact area, etc. Touch and step voltages can also be calculated using software tools, such as WinIGS or GroundMat, that perform touch and step voltage calculations and analysis.


Q4: How to perform lightning protection using earthing design software?




A4: Lightning protection is the process of designing and installing a system that protects an electrical power system from lightning strikes and surges. It involves three main components: air terminals, down conductors, and earthing electrodes. Earthing design software can help you to perform lightning protection calculations and simulations, such as lightning strike frequency, lightning current waveform, lightning impulse withstand voltage, etc. Earthing design software can also help you to design and optimize your earthing electrodes for lightning protection, such as rods, plates, grids, etc., using various methods and parameters. Some of the earthing design software packages that support lightning protection features are CDEGS, XGSLab, and Sesame.


Q5: How to validate and verify the results of earthing design software?




A5: Validation and verification are important steps that ensure the accuracy and reliability of the results of earthing design software. Validation is the process of comparing the results of earthing design software with experimental or field data, to check if they match within an acceptable range of error. Verification is the process of comparing the results of earthing design software with analytical or theoretical solutions, to check if they follow the same principles and assumptions. Validation and verification can be done using various methods and tools, such as measurement devices, test equipment, reference books, etc. dcd2dc6462
