About This Item
IEEE 356-2020 is a technical guide for measurements of the electromagnetic properties of earth media, helping engineers and testers evaluate how soil and related ground materials behave under electrical fields. In the context of fields, waves, and electromagnetics, it supports more consistent measurement practice for applications where ground characteristics affect system design, modeling, and performance. IEEE 356-2020 is useful when reliable earth-property data is needed to reduce uncertainty in analysis and testing.
Overview of IEEE 356-2020
This standard addresses measurement methods for electromagnetic properties of earth media, with emphasis on obtaining data that can be used in engineering calculations and field evaluations. It is relevant to work involving ground conductivity, permittivity, and related parameters that influence how electromagnetic energy interacts with the earth. As a guide, IEEE 356-2020 helps provide a common technical basis for measurement planning, instrument use, and interpretation of results in practical engineering environments.
Typical use cases
IEEE 356-2020 is typically used when measuring soil or earth media for power, grounding, and electromagnetic compatibility studies, as well as for modeling field behavior near the ground surface. It may support test programs for substations, transmission corridors, buried conductors, antennas, and other installations where earth properties affect performance. The standard is also useful in laboratory and field workflows that compare sites, document material behavior, or validate assumptions used in engineering analysis.
Why it matters
Accurate measurement of earth media properties can materially affect design decisions, compliance work, and risk reduction in electrical systems. IEEE 356-2020 helps improve consistency across measurements, which is important when results are used for simulation inputs, grounding design, or performance verification. By offering a shared reference for how such properties are measured, the standard can reduce ambiguity, support procurement and specification work, and make technical conclusions easier to defend.
