CDEGS
vertical specialistEngineering software suite for grounding, electromagnetic fields, and lightning protection analysis.
Batch study reruns with stored model inputs enables fast iteration and consistent report generation across design alternatives.
Lightning protection studies in CDEGS typically use a geometric model of structures, air-termination systems, and electrode layouts to compute field and grounding responses needed for protection design. The workflow stays concentrated on electrical behavior outputs, including step and touch related contours and transient-related results used to assess surge coordination impacts. Report generation can be kept consistent across iterations by storing the same geometry and parameter sets and re-running the selected studies.
A key tradeoff is that advanced automation and integration options are more limited than in general engineering platforms that expose REST APIs for provisioning, in-house extensions, and external orchestration. CDEGS fits best for contractors and facilities teams that manage protection design cycles inside a controlled modeling process and need stable, repeatable study reports rather than deep system integration.

How to Choose the Right Lightning Protection Software
Lightning protection software choices differ most in how reliably they turn design inputs into protection coverage, documentation, and audit-ready outputs. We focus on criteria like protection model traceability so you can verify assumptions, outputs, and revisions match the files you’ll actually submit.
Risk assumptions and input coverage
Why it matters
When lightning protection model assumptions are unclear, the final recommendations can drift from the site you’re responsible for. Risk assumptions and input coverage keeps the workflow honest and reproducible.
How to check
Ask the demo to show a complete checklist of required site inputs, then point out what the tool does when inputs are missing. Export a sample report and confirm the documented assumptions match what you entered.
Protection coverage calculation transparency
Why it matters
Protection coverage calculation transparency matters because buyers must see how the tool decides whether areas are covered. Without transparent calculations, you can’t explain or defend decisions during review.
How to check
Provide the tool a simple test case site and ask it to display the coverage method it uses and the intermediate results it logs. Compare the exported diagrams or tables against what the on-screen steps claim.
Drawings and report export fidelity
Why it matters
Lightning protection documentation often gets reused across permits, inspections, and maintenance. Drawings and report export fidelity ensures the figures and text you send are the ones generated from the same model.
How to check
Generate one project with multiple structures, then export at least one PDF and one editable drawing package. Check that labels, structure identifiers, and revisions in the exports match the model name and input set.
Scenario versioning and revision history
Why it matters
Lightning protection projects change during design iterations and field verification. Scenario versioning and revision history helps you prove what changed, when, and why.
How to check
In the demo, modify a key input (like structure geometry or conductor layout) and track how the project history records the change. Export a revision-linked report and confirm the timestamps and notes map to the edits.
API and automation for batch projects
Why it matters
Large site portfolios and repeat designs require dependable automation around project setup and output generation. A clear automation and API surface reduces manual re-entry and mistakes.
How to check
Ask for an example workflow that provisions a project from an external data file and returns calculated outputs. Validate that the outputs are deterministic by running the same input twice and diffing the results.
Data model and import template control
Why it matters
If import templates don’t map cleanly to how designs are represented, you’ll spend time correcting data and risk silent mismatches. Data model and import template control keeps the model inputs consistent.
How to check
Request the import template for site geometry, structure attributes, and conductors, then try importing a small dataset in the demo environment. Confirm the tool flags missing fields and shows a clear mapping from import columns to model fields.
Red flags
- Outputs don’t explain the underlying protection coverage calculations clearly.
- Exports show diagrams or labels that don’t match the current model inputs.
- Revision history doesn’t record what changed or ties edits to the reports.
Fit by situation
- If you often update site measurements during design reviews, prioritize scenario versioning and revision history.
- If you need to defend assumptions to reviewers, prioritize protection coverage calculation transparency.
- If you manage many similar sites via repeatable workflows, prioritize API and automation for batch projects.
