What is IEEE 80?
IEEE 80 is a guide for safety in AC substation grounding, published by the Institute of Electrical and Electronics Engineers (IEEE). It was first issued in 1961 and has been revised several times since then. The latest version is IEEE 80-2013, which incorporates a corrigendum from 2015.
IEEE 80 is primarily concerned with outdoor AC substations, either conventional or gas-insulated. These include distribution, transmission, and generating plant substations. With proper caution, the methods described in IEEE 80 are also applicable to indoor portions of such substations, or to substations that are wholly indoors. However, IEEE 80 does not cover the grounding problems peculiar to DC substations or the effects of lightning surges.
The intent of IEEE 80 is to provide guidance and information pertinent to safe grounding practices in AC substation design. The specific purposes of IEEE 80 are to:
Establish, as a basis for design, safety limits of potential differences that can exist in a substation under fault conditions between points that can be contacted by the human body.
Review substation grounding practices with special reference to safety, and develop safety criteria for design.
Provide a procedure for the design of practical grounding systems, based on these criteria.
Develop analytical methods as an aid in the understanding and solution of typical voltage gradient problems.
Provide benchmarks cases to compare the results of IEEE 80 equations to commercially available software programs.
Why is IEEE 80 important?
Safety benefits
One of the main reasons why IEEE 80 is important is because it helps to ensure safety in AC substation grounding. Grounding is the process of connecting electrical equipment or conductors to the earth or a common point of reference. Grounding serves several purposes, such as:
Providing a path for fault currents to flow safely to earth.
Limiting the voltage rise on equipment and conductors during faults or surges.
Stabilizing the voltage level on the system during normal operation.
Reducing electromagnetic interference and noise.
If grounding is not done properly, it can pose serious hazards to people and equipment in or near the substation. Some of the potential risks include:
Electric shock or electrocution due to contact with energized parts or ground potential rise.
Fire or explosion due to arcing or overheating of equipment or conductors.
Damage or malfunction of equipment due to overvoltage or insulation failure.
IEEE 80 helps to prevent these hazards by providing safety limits of potential differences that can exist in a substation under fault conditions between points that can be contacted by the human body. These limits are based on the tolerable body current and the body resistance of a person in contact with the ground. IEEE 80 also provides methods for calculating the ground potential rise, the touch and step voltages, and the ground resistance of various grounding systems.

Design benefits
Another reason why IEEE 80 is important is because it provides a procedure for designing practical grounding systems based on safety criteria and analytical methods. A grounding system consists of all the components that are used to establish a low-resistance connection to earth, such as ground rods, cables, grids, mats, plates, etc. The design of a grounding system involves several factors, such as:
The type and configuration of the substation and its equipment.
The soil resistivity and structure.
The fault current magnitude and duration.
The environmental and climatic conditions.
The cost and availability of materials and labor.
IEEE 80 helps to optimize the design of a grounding system by providing a step-by-step procedure that includes:
Selecting a suitable layout and size for the ground grid.
Determining the number and location of ground rods.
Calculating the ground resistance and impedance of the grounding system.
Evaluating the ground potential rise, the touch and step voltages, and the mesh and equipotential voltages.
Comparing the results with the safety criteria and making adjustments if necessary.
Using software tools or field measurements to verify the design.
Compliance benefits
A third reason why IEEE 80 is important is because it helps to meet the regulatory and industry standards for substation grounding. Depending on the location and jurisdiction of the substation, there may be different codes, rules, or regulations that apply to its grounding system. Some of these include:
National Electrical Code (NEC).
National Electrical Safety Code (NESC).
Occupational Safety and Health Administration (OSHA).
Electric Power Research Institute (EPRI).
North American Electric Reliability Corporation (NERC).
IEEE 80 helps to comply with these standards by providing a common reference and framework for substation grounding. It also provides recommendations and best practices that are consistent with the latest research and development in the field. By following IEEE 80, substation owners and operators can ensure that their grounding systems are safe, reliable, and efficient. How to download IEEE 80?
