Comparison Table
SKM Power*Tools
grounding analysisSKM Power*Tools performs grounding and electrical system studies that support selection of protective and grounding arrangements used in lightning protection engineering.
Zone and component-based calculation based on a structured protection system model.
SKM Power*Tools runs lightning protection calculations from input models of structures, components, and protection zones. It provides a calculation workflow that outputs engineering results tied to a defined schema of objects and parameters.
The application supports model reuse across projects through configurable settings and repeatable calculation tasks. Integration depth is mostly inside the tool, since the automation and API surface is not documented in the same way as calculation engines with public endpoints.
- +Calculation workflow tied to structured lightning protection input objects
- +Configurable project settings support repeatable calculations across similar assets
- +Model outputs map to engineering elements like zones and system components
- –Public documentation for API and automation hooks is not evident
- –External integration requires file or manual export paths rather than provisioning
- –Admin governance features like RBAC and audit logs are not clearly surfaced

Best for: Fits when teams need consistent lightning protection outputs inside a single modeling tool.
AutoCAD Electrical
CAD-basedAutoCAD Electrical supports structured electrical design data and drawing-driven engineering workflows that can be used to document lightning protection system components and connections.
Project-level tag and attribute management that drives consistent component labeling across electrical drawings.
AutoCAD Electrical keeps a project-level structure for electrical drawings, including tag management, component lookup, and consistency checks across related sheets. For lightning protection calculations, the practical fit is generating and maintaining the documentation layer that mirrors the engineering model, such as down conductor routes and connection callouts. The schema is rooted in CAD entities, block attributes, and symbol metadata, so the same attributes can flow into BOM and drawing reports.
Automation and extensibility tend to operate on drawing content, which works well for repeatable layouts and annotation standards. A concrete tradeoff is that throughput for calculations depends on external analysis workflows, since the CAD environment primarily manages documentation rather than performing full lightning parameter calculations as a built-in computation service. This usage pattern fits teams that already standardize electrical symbol tags and want lightning protection documentation to inherit those conventions with controlled generation.
- +Shared CAD data model links tags, attributes, and symbol libraries across drawings
- +Automated drawing generation from templates reduces manual wiring diagram edits
- +Extensible symbol and attribute schema supports standards-based documentation
- –Calculation logic is not a dedicated lightning analysis workflow inside the CAD model
- –Automation control is mainly drawing-centric, limiting external API-first integration
- –Governance relies on CAD workspace processes rather than centralized RBAC and audit tooling

Best for: Fits when electrical teams automate lightning documentation generation from tagged CAD projects.
EasyPower
engineering calculationsEasyPower supports electrical calculations for power systems and grounding conditions that can feed lightning protection system design documentation.
Project-based configuration of input parameters tied to calculation outputs.
EasyPower targets Lightning Protection Calculation workflows with a structured data model for coefficient inputs, risk parameters, and calculated results. The tool supports repeatable project configuration so teams can run consistent studies across sites and revisions.
Integration depth depends on how freely the system exports calculation artifacts and parameter sets for downstream documentation and approval processes. Automation and API surface appear limited from the published product materials, so orchestration typically relies on manual project operation and file-based handoff.
- +Structured project configuration keeps coefficient inputs and results consistent
- +Repeatable runs support revision tracking across design iterations
- +Exportable calculation outputs fit common reporting and documentation workflows
- –API and automation surface are not clearly documented for provisioning workflows
- –Governance controls like RBAC and audit logs are not clearly specified

- +Automation supports repeatable setup across multiple projects and assets
- +RBAC restricts who can edit protections and who can run calculations
- –API surface is limited compared with tools that expose full calculation endpoints

How to Choose the Right Lightning Protection Calculation Software
Options separate by how faithfully they compute and how controllable they are for real-world inputs. The biggest differences show up in the data you can feed and verify, plus whether the workflow can produce repeatable outputs using the same calculation choices, especially in the criterion labeled Calculation transparency and traceability.
Input coverage for structure and environment
Why it matters
Lightning protection calculation depends on details like geometry, elevations, and nearby features. If Input coverage for structure and environment is thin, the software will push you into assumptions you cannot justify later.
How to check
Start a demo project using a small sample model (or provided example) and change structure height, roof form, and surrounding object distances. Ask whether the software accepts those fields directly and shows which inputs affect the results.
Calculation transparency and traceability
Why it matters
When Calculation transparency and traceability is weak, results look like a black box. For liability and review, you need to see what was selected and what drove each output.
How to check
Request an export or report view that lists calculation steps and key selections used. Check whether you can reproduce the same output after changing one input (e.g., conductor height) and see exactly what changed.
Output clarity with engineering-ready reports
Why it matters
Lightning protection calculations get used in documentation, not just screenshots. Output clarity with engineering-ready reports matters when you need readable assumptions, units, and consistent formatting across scenarios.
How to check
Export results in at least two formats supported by the tool and compare them for unit consistency and label clarity. Then run a second scenario and verify the report updates without missing sections.
Calculation method controls and assumptions
Why it matters
Different projects require different calculation choices, and default assumptions can hide gaps. With Calculation method controls and assumptions, you can align the computation workflow with your review expectations.
How to check
On a demo, locate where methods or parameters are selected and what default values are applied. Change one method/assumption and confirm the outputs change in a way that matches the description shown in the UI.
Batch runs and scenario management
Why it matters
Lightning projects often iterate through multiple variants. Workflow automation for batch runs and scenario management reduces rework and keeps comparisons consistent.
How to check
Ask for a way to duplicate a project as a new scenario and run multiple cases without manual clicking each time. Check whether results remain tied to the scenario inputs and whether exports keep the scenario identifiers.
Versioning for results and saved inputs
Why it matters
Re-running months later is common, and results must be defensible. Versioning for results and saved inputs helps you confirm which inputs and settings produced a given output.
How to check
In the demo, modify an input and then restore or view prior versions of the project. Check whether the tool records a calculation configuration snapshot (not just the final document).
Red flags
- Results change when you edit inputs, but the report does not clearly show what drivers were used.
- The tool only provides a summary number without any step-by-step calculation trace or selections.
- You can’t run or compare multiple scenarios while keeping outputs correctly mapped to their inputs.
Fit by situation
- If you handle frequent roof and site geometry variants, prioritize Input coverage for structure and environment.
- If your deliverable gets reviewed by others, prioritize Calculation transparency and traceability.
- If you iterate through many cases and need comparisons, prioritize Batch runs and scenario management.
