SKM Power*Tools
enterpriseSKM Power*Tools analyzes electrical distribution systems and includes grounding study capabilities.
Case-based earthing studies that preserve grounding geometry and reuse the calculation context across iterations.
Earthing studies in SKM Power*Tools are driven by user-defined electrode geometry and electrical inputs, then calculated outputs feed directly into compliance-style evaluations such as touch and step voltage limits. Conductor layout and grounding arrangement inputs are central to the approach, which helps avoid manual relabeling when grids are reconfigured. Results can be generated for multiple design cases without rebuilding the calculation definition each time.
A tradeoff appears when projects require deep interoperability with non-SKM design toolchains, because the strongest continuity is within SKM workflows rather than across many third-party CAD and simulation formats. SKM Power*Tools fits projects where engineers need repeatable substation grounding and earthing studies aligned with power-system study assumptions.
- +Geometry-driven grounding grid studies with consistent electrode modeling
- +Direct calculation outputs for touch and step voltage risk assessment
- +Supports iterative case runs for fault and soil assumption changes

How to Choose the Right earthing calculation software
Earthing calculation software turns modeled grounding geometry and soil resistivity assumptions into earth electrode resistance and touch and step voltage risk outputs for earth fault scenarios. This buyer’s guide covers SKM Power*Tools, CDEGS, and ETAP first, then compares EasyPower, PowerFactory, XGSLab, SafeGrid Earthing, ECalPro Earthing Calculator, CYMGRD, and AutoGroundDesign.
The tools differ most in how study context stays consistent across iterations, how tightly earthing inputs stay coupled to power-system fault inputs, and how calculation runs handle repeatability for multiple sites and scenarios. SKM Power*Tools emphasizes case-based studies that preserve grounding geometry and reuse the calculation context, while CDEGS focuses on a linked workflow that drives safety voltage outputs from soil layering assumptions.
Earthing calculation software for grounding grid and safety voltage studies from soil and geometry models
Earthing calculation software supports grounding grid design workflows that compute earth resistance and safety voltage outputs such as touch voltage and step voltage from electrode and conductor layouts plus soil resistivity inputs. Many systems also incorporate earth fault current distribution inputs so the earthing results remain aligned with the electrical study context.
SKM Power*Tools is built around case-based earthing studies that preserve grounding geometry and reuse the calculation context across iterations, which reduces drift when models evolve. CDEGS uses a single study workflow that links soil layering assumptions to touch and step voltage outputs for earth fault conditions, which keeps safety voltage outputs consistent with the modeled soil behavior.
Earthing calculation selection checklist for geometry, soil layering, and safety outputs
Earthing calculation software must convert electrode and conductor geometry plus soil resistivity assumptions into earth electrode resistance and safety voltage outputs like touch voltage and step voltage under earth-fault conditions. The calculation workflow matters because teams need repeatable safety voltage results when they iterate geometry, soil layering, and fault assumptions across scenarios.
Across SKM Power*Tools, CDEGS, ETAP, and EasyPower, the biggest differentiator is whether earthing runs stay inside the broader electrical or study context or run as an isolated earthing calculation workflow. The same need shows up in interchange-heavy projects where geometry changes must not corrupt safety voltage outputs.
Study-context coupling for earth-fault consistency
ETAP and PowerFactory tie earthing outputs to the surrounding electrical study context so earth-fault and related inputs stay synchronized across iterations. SKM Power*Tools also produces earthing results inside its power-system study context so step and touch voltage outputs align with modeled conditions.
Linked soil layering workflow to safety voltage outputs
CDEGS uses a single study workflow that links soil layering assumptions to touch and step voltage outputs for earth-fault conditions. EasyPower similarly supports layered soil resistivity modeling so step and touch voltage outputs map directly to earth fault risk checks.
Case-based repeatability that preserves grounding geometry
SKM Power*Tools runs case-based earthing studies that preserve grounding geometry and reuse the calculation context across iterations. XGSLab supports project templates that standardize repeated grounding scenarios and minimize input drift during iterative design reviews.
Grid-layout-first conductor geometry workflow
SafeGrid Earthing uses a grid-layout-first workflow that connects conductor geometry to touch and step voltage outputs within one project model. EasyPower and SKM Power*Tools also compute grid and electrode resistance and convert those results to safety voltage checks.
Automation and throughput for multi-site scenario runs
XGSLab focuses on scenario-driven modeling and templates to reduce input drift but has limited integration automation compared with enterprise stacks. AutoGroundDesign emphasizes input-first project workflows and keeps automation depth tied to how much the process is covered by built-in templates.
Interoperability paths for CAD and exchange workflows
CDEGS can require format-specific cleanup for DXF-driven layouts when interoperability paths meet complex geometry. SafeGrid Earthing and AutoGroundDesign provide more limited CAD interoperability features than CAD-first workflows.
Electrode-focused resistance workflow for fast checks
ECalPro Earthing Calculator is tailored to earth electrode resistance calculations across electrode geometry variants in a calculator flow. CYMGRD supports constrained grounding-centric iterations so earth resistance results stay tied to grounding performance inputs across alternative configurations.
Choose by workflow philosophy and integration depth across study, geometry, and automation
Two projects can use the same safety voltage criteria and still fail the acceptance process if earthing inputs and electrical fault assumptions are not kept consistent across iterations. The decision framework below separates tools that embed earthing in broader study contexts from tools that centralize earthing workflow repeatability.
The second decision axis is how grid and electrode geometry gets stabilized across iterations. Tools with case-based or template-driven runs reduce input drift when teams handle multiple sites and recurring substation layouts.
Pick embedded study coupling when electrical fault context must stay synchronized
Choose ETAP or PowerFactory when earth-fault inputs and related electrical scenarios must remain in the same controlled study environment as earth-fault safety outputs. Choose SKM Power*Tools when repeatable earthing outputs need to be generated inside a power-system study context while preserving grounding geometry across case iterations.
Pick linked earthing workflow when soil layering drives safety voltages as a single chain
Choose CDEGS when the study workflow needs to connect soil layering assumptions directly to touch and step voltage outputs for earth fault conditions. Choose EasyPower when layered soil resistivity modeling must support grounded risk checks with direct mapping from soil behavior assumptions to step and touch voltage outputs.
Pick case-based or template-driven repeatability to reduce drift across iterations
Choose SKM Power*Tools when case-based studies must preserve grounding geometry and reuse calculation context across design iterations. Choose XGSLab when project templates must standardize repeated grounding scenarios so electrode and grid resistance workflows remain consistent across alternative cases.
Pick grid-layout-first workflows when conductor geometry drives the project model
Choose SafeGrid Earthing when substation teams need a grid-layout-first model that ties grid conductor layout to resistance and voltage outputs. Choose EasyPower or ETAP when the project needs grid voltage checks but also needs direct alignment with electrical fault study assumptions.
Pick electrode-focused calculators when the scope is fast earth electrode resistance checks
Choose ECalPro Earthing Calculator when the workflow center is earth electrode resistance calculation across electrode geometry variants in a focused calculator flow. Choose CYMGRD when alternative grid and electrode configurations need constrained grounding-centric iterations with consistent earth resistance assumptions.
Pick integration-tolerant tools when CAD exchange and automation are constrained
Choose SKM Power*Tools or CDEGS when DXF-driven layouts must land into a workflow that produces consistent safety voltage outputs even as geometry complexity grows. Choose AutoGroundDesign or SafeGrid Earthing when the team can manage data exchange manually and accept limited CAD interoperability for complex electrode assemblies.
Who benefits from earthing calculation software with embedded context, repeatability, and geometry control
Earthing calculation software fits teams that must translate grounded geometry and soil resistivity assumptions into safety voltage outputs and earth electrode resistance with repeatable results. The strongest fit depends on whether teams run earthing in isolation or keep it synchronized with electrical fault studies.
Teams also benefit when the tool reduces input drift during iterative redesign across sites. Case-based studies, template-driven scenarios, and grid-layout-first models directly address that failure mode.
Power utility substation grounding engineers running repeatable case studies
SKM Power*Tools supports case-based earthing studies that preserve grounding geometry and reuse calculation context across iterations. That design reduces drift when substation grounding geometry evolves while electrical study context remains stable.
Industrial teams that need a single soil layering to safety voltage workflow
CDEGS provides one study workflow that links soil layering inputs to touch and step voltage outputs for earth fault conditions. The integrated chain keeps safety voltage outputs consistent with modeled soil behavior across revisions.
Electrical engineering groups that require synchronized earthing and fault-study assumptions
ETAP and PowerFactory generate safety voltage outputs from modeled conditions inside broader electrical study flows. That coupling helps avoid inconsistencies when system assumptions change across electrical scenarios.
Substation design teams that treat grid conductor layout as the primary model
SafeGrid Earthing connects grid conductor layout to resistance and touch and step voltage outputs within one project model. The grid-layout-first approach supports repeatable grid calculations when conductor geometry is the main driver.
Engineering teams focused on fast electrode resistance variants with fewer grid complexities
ECalPro Earthing Calculator keeps the workflow centered on earth electrode resistance calculation across electrode geometry variants. CYMGRD targets constrained grounding-centric iterations for earth resistance across alternative configurations.
Common earthing calculation mistakes that break repeatability and acceptance outcomes
Earthing projects fail when geometry assumptions and soil parameters drift across iterations or when imported geometry does not match modeled conductor layouts. Calculation tools can still produce outputs that look correct even when input provenance changes between runs.
Mistakes often show up as inconsistent safety voltage results when teams move between earthing-only workflows and electrical study contexts, or when interoperability cleanup changes electrode connectivity and spacing.
Treating earthing runs as independent when electrical fault assumptions must stay synchronized
Use ETAP or PowerFactory when earthing results must be generated inside the same electrical study context so earth-fault and related inputs remain consistent. If earthing is isolated in a separate workflow, teams need a repeatable handoff mechanism to prevent assumption drift.
Letting soil layering complexity grow without a workflow that ties inputs to touch and step voltage outputs
Choose CDEGS when the study chain must link soil layering assumptions directly to safety voltage outputs for earth fault conditions. If soil layering changes are managed outside the linked workflow, teams must track which safety outputs correspond to which soil parameter sets.
Assuming CAD interchange preserves geometry details without cleanup or validation
Plan validation when CDEGS DXF-driven layouts require format-specific cleanup, because geometry cleanup can change conductor geometry inputs used by voltage calculations. Use SafeGrid Earthing or AutoGroundDesign only when limited CAD interoperability aligns with the project’s exchange discipline.
Repeatedly retyping or re-importing geometry in iterative design cycles
SKM Power*Tools and XGSLab reduce input drift through case-based studies and project templates that standardize repeated scenarios. Manual transcription across runs tends to produce inconsistent electrode or grid assumptions even when teams reuse the same safety criteria.
Overextending electrode-focused workflows to full grounding grid deliverables
ECalPro Earthing Calculator is designed around earth electrode resistance checks for electrode geometry variants, so it is not a substitute for grid conductor layout design workflows. Use grid-focused tools like SafeGrid Earthing or EasyPower when the deliverable requires touch and step voltage outputs tied to detailed grid conductor layouts.
