ELCAD: Lightning Protection

CAD-integrated

ELCAD provides lightning protection design and calculation workflows inside its electrical CAD environment for air-termination, down-conductor, and earthing layouts.

9.5/10
Overall
Features9.2/10
Ease of Use9.7/10
Value9.7/10
Standout feature

Calculation definition templates that standardize protection parameters across multiple project reruns.

ELCAD’s core capability is producing lightning protection calculation results from a defined input schema that covers site geometry and protection system elements. The data model supports importing and maintaining project inputs over time so that reruns use the same calculation setup. Calculation configuration is explicit, including selection of protection approach parameters and handling of measurement and topology inputs.

A tradeoff is that deep customization depends on how well teams map their engineering conventions into ELCAD’s calculation setup fields. It fits situations where multiple projects share consistent methodology and where auditability of calculation parameters matters for handover and internal review.

Pros
  • +Explicit calculation setup captures method parameters for consistent reruns
  • +Structured project data model organizes conductors, zones, and earth systems
  • +Automation via saved calculation definitions reduces manual re-entry
  • +Repeatable inputs support review workflows across engineering iterations
  • +Clear separation between geometry inputs and protection configuration
Cons
  • Customization depends on fitting engineering conventions into its schema
  • Automation surface is narrower than full programmable APIs

Best for: Fits when teams need repeatable lightning calculations from consistent project data and governed setups.

#2

EPLAN

engineering suite

EPLAN supports electrical design documentation and engineering calculations that can be used to structure lightning protection system schematics and related electrical documentation.

9.1/10
Overall
Features9.0/10
Ease of Use9.4/10
Value9.0/10
Standout feature

Project-template driven calculation parameter provisioning with structured report outputs.

Lightning protection calculation work typically depends on consistent input geometry, standards references, and placement assumptions, and EPLAN keeps those inputs aligned to structured engineering objects. The data model supports traceable configuration and repeatable report generation, so changes in project setup propagate through downstream calculation artifacts. EPLAN also supports integration with surrounding engineering processes, which matters when drawings, bills of materials, and documentation must stay synchronized.

A tradeoff is that EPLAN’s calculation workflow is constrained by the broader engineering project model, so teams that only need a standalone computation may face extra setup for schema alignment. EPLAN fits teams that run frequent revisions, maintain audit trails across releases, and need consistent parameter sets for calculation throughput across many projects.

Pros
  • +Structured engineering data model links inputs to calculation outputs
  • +Repeatable calculation and document generation via project configuration
  • +Integration depth reduces manual re-entry across engineering artifacts
  • +Automation through reusable project templates and parameter governance
Cons
  • Standalone lightning calculations require additional model setup
  • Automation requires alignment with EPLAN schema and configuration patterns

Best for: Fits when engineering teams need governed lightning calculations embedded in project workflows.

#3

AutoCAD Electrical

CAD-based

AutoCAD Electrical supports structured electrical design data and drawing-driven engineering workflows that can be used to document lightning protection system components and connections.

8.8/10
Overall
Features8.8/10
Ease of Use8.8/10
Value8.9/10
Standout feature

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.

Pros
  • +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
Cons
  • 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.

#4

How to Choose the Right Lightning Protection Calculation Software

This buyer’s guide covers lightning protection calculation software tools used to run repeatable LPS design calculations and generate protection requirements from structured inputs. It focuses on ELCAD: Lightning Protection, EPLAN, AutoCAD Electrical, ETAP, SKM Power*Tools, EasyPower, XTRACT, AeroCAD 4D, CitelNET, and LightningCAD.

The guide compares integration depth, data model behavior, automation and API surface, and admin governance controls across CAD, electrical, and calculation-centric workflows. It also turns those differences into concrete selection steps with tool-specific checks for schema fit, traceability, and repeatable reruns.

Software that calculates lightning protection requirements from a governed engineering data model

Lightning protection calculation software converts structured conductor, air-termination, down-conductor, and earthing inputs into protection zones and calculation results that remain traceable back to those objects. Tools like ELCAD: Lightning Protection and EPLAN tie geometry and configuration to structured project data so reruns stay consistent across engineering iterations.

These tools reduce manual re-entry of method parameters and calculation setups by using templates and configuration patterns that connect inputs to derived outputs. ETAP and SKM Power*Tools also keep results tied to electrical topology and zone components so engineers can trace assumptions through runs.

Integration depth and governance controls that keep lightning calculations consistent

Evaluating these tools means checking how the data model connects geometry inputs to protection configuration and how automation preserves that mapping across project revisions.

    ELCAD: Lightning Protection automates through saved calculation definitions and configuration exports, which supports repeatable engineering runs but has a narrower automation surface than programmable calculation endpoints. ETAP supports scripting and project-level operations, so it fits teams that standardize setup across many assets while still keeping governance tied to project elements.

  • Verify governance controls for who can edit inputs and run calculations

    If controlled engineering change management is required, ETAP provides RBAC and audit logs for model and calculation input changes. If governance must be centralized beyond templates, confirm whether tools like SKM Power*Tools, EasyPower, and LightningCAD provide clearly surfaced RBAC and audit logging behavior for calculation rules.

  • Align document output needs with the tool’s structured reporting attachments

    EPLAN provides repeatable calculation and document generation driven by project configuration, which reduces disconnect between calculated requirements and documentation artifacts. CitelNET ties generated documentation outputs to installation context, while XTRACT exports artifacts intended for downstream review and documentation workflows.

Which lightning protection calculation workflows fit each tool’s integration style

Different teams need different integration depth levels and different levels of governance control. Some teams prioritize template-driven repeatability inside a lightning-focused workflow, while others prioritize embedding lightning calculations into a broader electrical or documentation pipeline.

The best fit depends on whether calculations must inherit electrical topology, whether documentation generation must remain tied to structured project data, and whether centralized RBAC and audit logs are required for controlled edits and reruns.

AutoCAD Electrical fits when lightning documentation generation must come from electrical tagged projects and component labeling conventions.

  • Teams that need lightning calculations tied to electrical topology with RBAC and audit logging

    ETAP fits when lightning protection models must stay consistent with electrical project topology and when role-based access controls and audit logging are required for controlled engineering changes. SKM Power*Tools fits teams that want zone and component-based calculation outputs inside a single modeling tool using structured protection system objects.

  • Organizations that require standardized report outputs tied to installation context

    CitelNET fits when teams need standardized lightning protection calculations and controlled report outputs by preserving installation-linked calculation context for documentation. EasyPower and ELCAD: Lightning Protection also support repeatable project configuration tied to calculation outputs, but governance tooling clarity is stronger in ETAP than in these other sets.

  • Teams where conductor placement geometry drives the calculation inputs across iterations

    AeroCAD 4D fits engineering teams needing a 4D-linked project data model that keeps calculation outputs connected across project updates. LightningCAD fits when geometry-to-calculation mapping keeps protective zones aligned with modeled conductors for export-driven workflows.

Pitfalls that cause drifting lightning calculations and weak control during revisions

Several recurring pitfalls come from mismatches between how lightning calculation inputs are modeled and how teams actually run revisions. Other failure modes appear when automation depth is assumed to match an API-first workflow or when governance requirements are underestimated.

The tools in this set expose these pitfalls through cons that describe narrower automation surfaces, weaker governance visibility, and schema customization friction when conventions do not match the tool’s data model.

  • Choosing a tool that can’t standardize method parameters across reruns

    Avoid selecting tools that require manual re-entry of method parameters if consistent reruns are the goal. ELCAD: Lightning Protection and EPLAN reduce drift by using calculation definition templates or project templates that provision consistent parameters for repeated runs.

  • Assuming CAD drawing automation equals lightning calculation automation

    AutoCAD Electrical automates drawing-centric workflows by tying tags, attributes, and symbol libraries to generated documentation, but it does not provide a dedicated lightning analysis workflow inside the CAD model. For calculation automation with controlled inputs, tools like ELCAD: Lightning Protection, ETAP, or SKM Power*Tools align better with structured calculation workflows.

  • Ignoring governance controls and audit traceability for calculation input changes

    ETAP is the clearest fit when centralized RBAC and audit logs are required for changes to model and calculation inputs. Tools like SKM Power*Tools, EasyPower, XTRACT, and CitelNET emphasize repeatable configuration and traceability, but the surfaced governance behavior is not described with the same RBAC and audit log granularity.

  • Overestimating extensibility when schema mapping requires tool-specific conventions

    ELCAD: Lightning Protection customization depends on fitting engineering conventions into its schema, which means custom workflows can require schema alignment work. EPLAN extensibility also depends on aligning to EPLAN schema and configuration patterns, and ETAP schema mapping for external data can require ETAP-specific mapping work.

How We Selected and Ranked These Tools

We evaluated each tool across three scored categories using the provided ratings for features, ease of use, and value, and then used a weighted average where features carried the most weight and ease of use and value each accounted for the remaining parts. Features availability and how directly the tool connects a structured data model to protection results carried more influence because calculation consistency and repeatability depend on those mechanics. This editorial ranking reflects criteria-based product positioning captured in the supplied tool summaries rather than hands-on lab testing.

ELCAD: Lightning Protection separated from the lower-ranked tools by combining a structured project data model with calculation definition templates that standardize protection parameters across multiple project reruns. That directly lifted the features and value outcomes because the tool reduces manual re-entry while keeping inputs and protection configuration clearly separated for consistent review cycles.

AeroCAD 4D focuses on a 4D-linked data model that keeps lightning protection inputs and calculation outputs connected across project updates, which reduces drift during migration between geometry iterations.
What are the typical causes of mismatched results when different teams run the same lightning calculation definition?
ELCAD targets this failure mode by using standardized calculation definition templates that reduce manual parameter re-entry. XTRACT addresses mismatches by using schema-backed project inputs and repeatable calculation runs so configuration changes and input edits produce reviewable artifacts rather than silent divergence.
Which products are most suitable when review workflows require auditable exports suitable for downstream approval?
XTRACT is designed to keep results attached to a structured data model and to maintain reviewable calculation artifacts for audit-style traceability. CitelNET publishes documentation tied to installation-linked context and structured parameters, which supports controlled report outputs for review and signoff.
When a project needs geometry-to-calculation mapping that stays aligned as models evolve, which tool fits best?
AeroCAD 4D keeps input geometry and lightning protection outputs connected through a 4D-oriented project data model, which supports stable mapping across updates.
