Top 10 Best Earthing Design Software of 2026

ETAP Ground Grid is built around grounding system design inputs such as grounding conductor routing, electrode geometry, and soil resistivity characterization. The core deliverables include earth potential rise, step voltage, and touch voltage outputs that support engineering reviews of substation and facility grounding grids. CAD-style geometry import is supported so grids can be mapped into the analysis model instead of being redrawn manually.

A practical tradeoff appears when projects require heavy custom computation beyond the built-in grounding checks, because deeper solver customization and external scripting are limited compared with code-first finite-element approaches. It fits best when an organization already uses ETAP studies and needs grounding results that stay consistent with the electrical fault assumptions used elsewhere in the model.

CDEGS supports grounding model building with selectable conductor and electrode representations, including buried conductor layouts and electrode assemblies suitable for substation, industrial, and telecom contexts. Results are generated for common safety metrics such as touch voltage and step voltage, and the software can evaluate earth potential rise and related fault conditions within the same project. The workflow reduces rework when multiple grid options share the same soil and fault assumptions. CAD import and export keep geometry consistent across design iterations and reviews.

A tradeoff is that advanced study automation relies more on analysts structuring projects and parameter sets than on a fully code-free, dashboard-style reporting layer. CDEGS fits when design teams run many variants of grid conductor sizing, mesh density, and electrode arrangement and need consistent outputs across those variants. It is also a fit when GIS and site layout inputs already exist in CAD or raster-derived drawings and must be converted into analysis-ready geometry.

PowerFactory supports earthing grid design workflows using detailed grounding system definitions, including buried conductor layouts and electrode elements. Soil resistivity modeling and earth potential results feed into safety checks that map to touch voltage and step voltage assessment practices. The same study environment can tie earth results to electrical network operation, which reduces translation work between separate tools. This integration depth suits organizations that already maintain DIgSILENT electrical models and need earthing consequences inside those studies.

A key tradeoff is that the earthing workflow depends on model setup discipline, because accurate soil and geometry inputs drive the quality of earth potential rise and fault distribution outputs. The best usage situation is a substation or industrial site where grounding design must be reviewed alongside short-circuit currents and fault scenarios rather than treated as an isolated calculation.

elec calc™ EP is an earthing design software used for engineering calculations around grounding system layouts and performance checks. It focuses on workflow-driven project handling with calculation modules for earth electrodes, conductor sizing, and voltage and potential risk outputs.

The tool supports file-based exchange for drawings and documentation work, with DXF export commonly used to carry geometry into CAD-centric processes. Its distinct value for earthing teams is repeatable calculation sets linked to a consistent project structure.

Earthing Calculator on elek.com computes grounding system results from electrode and soil inputs and returns engineering outputs needed for earthing grid design studies. It supports common electrode geometry and soil resistivity approaches such as the Wenner four-point method to parameterize ground models.

It also focuses on quick iterative checking for earth resistance, touch and step voltage limits, and related fault current distribution inputs without requiring a full GIS or CAD toolchain. Workflow speed and repeatability come from keeping assumptions explicit through the input-driven configuration model.

Grounding Grid Design Module in PSS®E integrates earthing grid design directly into the Siemens power system workflow, so grid calculations stay tied to the network model used for steady-state studies. The module supports buried conductor layout generation and iterative sizing using grounding performance checks used in substation grounding studies.

It fits teams that need repeatable grounding results inside an engineering environment that already manages cases and revisions through PSS®E projects. Automation comes mainly through project-driven workflows and model-to-module handoffs rather than separate grid-specific scripting.

XGSLab is focused on engineering workflows for grounding system design and it ties calculations to a project workspace instead of treating each report as a standalone export. The tool supports grid and electrode layout work where conductor geometry, soil assumptions, and grounding performance checks stay linked across iterative updates.

XGSLab also covers soil resistivity modeling inputs used for fault and voltage evaluations, which reduces the risk of copying inconsistent assumptions between revisions. CAD interoperability for grounding layouts helps move between drawing tools and the design calculations without rebuilding geometry each cycle.

ProVision from powerprojects.co.za targets earthing grid design work by combining calculation workflows with documentation outputs used in grounding system design deliverables. The tool supports earth-electrode and conductor layout workflows that map from site input to sizing results used in grid conductor selection and grounding arrangement review.

ProVision also focuses on repeatable engineering runs, which helps teams standardize calculations across projects and versions of assumptions. CAD-oriented handoff is handled through export options used for buried conductor layout communication alongside design spreadsheets.

Grounding in PSCAD models earthing and grounding system behavior inside the PSCAD electromagnetic and power system simulation environment. It supports conductor network representation and fault and transient scenarios to compute earth potential rise and related voltage stress at defined points.

The workflow ties grounding calculations to time-domain simulation results, which makes it useful for validating how a ground network interacts with switching or fault waveforms. Compared with dedicated earthing design tools, it is most distinct when grounding performance must be checked alongside detailed power-system transients rather than only using standalone sizing checks.

CYMGRD from cyme.com is an earthing grid design tool focused on producing design results from electrode and conductor layouts tied to soil model inputs. The workflow centers on entering grounding system geometry, running electrical calculations, and outputting engineering deliverables aligned to common earthing assessment outputs.

It supports CAD-friendly geometry exchange with DXF-based workflows and exportable artifacts for downstream drafting and review cycles. The strongest fit is teams that already standardize their design inputs and want repeatable calculations across multiple grid and electrode variants.
