Comparison Table
EasyPower
enterpriseElectrical system analysis software covering arc flash, short circuit, coordination, and incident energy calculations.
Revision-linked arc flash reports map incident energy and boundary changes back to specific equipment and device settings.
EasyPower supports arc flash boundary outputs for multiple approach distances and converts fault clearing outcomes into incident energy at working distance values that drive PPE category selection. The workflow connects modeled protective device behavior, clearing time inputs, and arcing fault assumptions into one repeatable study run. Documentation-style reports link back to the model elements so changes to devices or settings can be traced to updated results.
A tradeoff appears in model dependency and data completeness. Results require accurate equipment and protective device parameters, so missing grounding, device settings, or conductor data often forces a study rebuild. EasyPower fits best when a team already maintains reliable one-line diagram content and wants repeatable arc flash updates after engineering changes.
- +Incident energy at working distance outputs tie directly to PPE category results
- +Arc flash boundary results support multiple approach distances for NFPA 70E labeling
- +Study elements link reports back to equipment and device inputs for revision traceability
- +File exchange workflows reduce re-entry when models exist in external design tools
- –Accurate results depend on complete equipment grounding and protective device settings
- –Large studies can take longer to validate due to model data consistency checks
- –Some automation requires disciplined template use and consistent study conventions
- –Cross-model merging can add manual cleanup when naming differs across sources

Best for: Fits when electrical teams need repeatable arc flash boundaries and PPE labeling from maintained one-line models.
ETAP
enterpriseElectrical power system software with arc flash analysis based on IEEE 1584 and related standards.
Arc flash results remain linked to the same protective device coordination study data used for updating clearing time and trip behavior.
ETAP’s arc flash workflow is driven by an electrical network model that stores equipment and protective device parameters used for incident energy analysis and boundary labeling. The tooling around study revision management supports iterative short-circuit study and coordination settings, then re-runs arc flash results against updated clearing time and trip settings. The result fits organizations that treat arc flash analysis as part of an engineered study set rather than a standalone report generator.
A key tradeoff is that teams get the most value when the one-line diagram model and protective device data are maintained with consistent study governance. ETAP fits best in environments with frequent study updates driven by load changes, equipment replacements, or coordination tuning, because revision discipline reduces rework across arc flash outputs.
- +Incident energy outputs tied to network model assumptions and device settings
- +Revision-oriented study workflow reduces rework across coordination and arc flash runs
- +Visual one-line review supports error spotting in device data and topology
- –Model quality strongly affects boundary labeling accuracy and study usability

Arc Flash Analytics is geared toward teams that build an electrical one-line diagram model, run arc flash hazard analysis, and then publish results tied to that model. It emphasizes repeatable calculation runs for protective device coordination workflows and documented equipment assumptions, which reduces drift between study iterations. Integration depth shows up through data import pathways that map equipment attributes into the analysis workspace.
A tradeoff appears when project needs require custom data structures beyond what its import mapping supports. It fits situations where multiple revisions are produced from a shared model and where consistent study formatting matters for internal review cycles.
- +Revision-linked studies reduce loss of assumptions between iterations
- +Export-ready outputs keep equipment assumptions and results traceable
- +Import mapping reduces manual entry for equipment attributes
- +Calculation workflows support coordination around clearing time inputs
- –Import mapping limits projects with highly custom equipment attributes

How to Choose the Right arc flash hazard analysis software
Arc flash hazard analysis software turns a one-line diagram plus protective device data into incident energy at working distance and arc flash boundary outputs for PPE labeling workflows. This guide covers EasyPower, ETAP, Arc Flash Analytics, SKM Power*Tools for Windows, CYME, PowerFactory, ECalPro Arc Flash Hazard Calculator, and ArcPro.
The review sequence focuses on what changes when study inputs evolve, including revision-linked report outputs and coordination-linked incident energy behavior. It also highlights where automation and repeatability differ, such as Easypower’s revision-linked mapping from boundary and incident energy changes back to equipment and device settings.
Arc flash hazard analysis software for incident energy and arc flash boundary calculations with revision-linked study workflows
Arc flash hazard analysis software computes incident energy at working distance and arc flash boundary results from short-circuit or protection study inputs for NFPA 70E-style labeling outputs. Many workflows also tie hazard outputs to protective device coordination so clearing time and trip behavior assumptions stay consistent across study revisions.
EasyPower links revision-linked arc flash reports so boundary and incident energy changes map back to specific equipment and device settings. ETAP keeps arc flash outputs linked to the same protective device coordination study data used for updating clearing time and trip behavior, which reduces reconciliation between coordination runs and hazard labeling updates.
Revision mapping, model coupling, and exportability for repeatable arc flash outputs
Arc flash hazard analysis depends on incident energy at working distance and arc flash boundary results that stay consistent when protective device inputs and model assumptions change. Features that preserve revision traceability reduce rework when one-line model updates ripple through coordination studies.
Revision-linked reporting that ties hazard changes back to settings
EasyPower maps boundary and incident energy changes back to specific equipment and protective device settings by linking revision behavior to arc flash report outputs. Arc Flash Analytics also ties arc flash boundary results to model and equipment assumptions across study iterations for documentation that stays traceable.
Coordination-linked incident energy that reuses the same study data
ETAP keeps arc flash results linked to the same protective device coordination study data used for updating clearing time and trip behavior. SKM Power*Tools for Windows anchors incident energy and arc flash boundary outputs in the study’s protection context so clearing time inputs remain consistent across revisions.
Boundary outputs aligned to multiple approach distances for labeling
EasyPower produces arc flash boundary results that support multiple approach distances for NFPA 70E labeling. ETAP focuses on revision-oriented workflows that reduce rework across coordination and arc flash runs when labeling updates must match clearing time behavior.
Controlled revision management across coordination and hazard workflows
CYME updates arc flash outputs from the same protection coordination study used for clearing time and device setting analysis to keep the two outputs aligned. ArcPro runs coordination outputs into arc flash boundary and PPE category reporting in a single study run while also supporting controlled revision updates.
Study workflow coupling strength across short-circuit and protection models
PowerFactory computes incident energy at working distance from faults and protective clearing behavior produced inside its protection study workflow. ECalPro Arc Flash Hazard Calculator derives incident energy and arc flash boundary results directly from bolted fault inputs plus protective device clearing characteristics without needing external model exchange.
Pick a workflow philosophy: revision-linked engineering tools or direct calculator inputs
The category splits into two practical workflow shapes: tools that reuse coordination and protection study outputs through revision-linked runs, and calculators that compute hazard results directly from fault inputs and protective device clearing characteristics. The right choice depends on how the organization maintains its network model, how often it revises device settings, and how much engineering governance is required across iterations.
Choose revision traceability depth for report-to-equipment accountability
If study outputs must map back to the specific equipment and device settings that changed, EasyPower is built around revision-linked arc flash reports that trace boundary and incident energy changes to maintained model entities. If the requirement is revision tracking for exportable traceability across study iterations, Arc Flash Analytics also links arc flash boundary results to model and equipment assumptions.
If coordination studies are already the source of truth, reuse them end-to-end
If clearing time and trip behavior already come from protective device coordination runs, ETAP keeps arc flash outputs linked to the same coordination study data and reduces reconciliation effort during labeling updates. If incident energy must stay anchored to protection coordination inputs where clearing time inputs remain consistent, SKM Power*Tools for Windows ties incident energy calculations and boundary outputs to the study’s protection context.
If the team maintains a shared coordination-and-clearing workflow, validate coupling behavior early
If arc flash boundary outcomes must update from the same protection coordination study used for clearing time, CYME couples the two workflows and supports study revision management for controlled iterations. If power system engineers already maintain model-driven protection study workflows, PowerFactory computes hazard outputs from faults and protective clearing behavior produced within that protection workflow.
If hazard computation must avoid external exchange, test direct fault input handling
If the workflow provides bolted fault current and protective device clearing characteristics and expects repeatable incident energy and boundary outputs without external exchange, ECalPro Arc Flash Hazard Calculator computes both directly from those inputs. If the organization already runs coordination outputs into hazard boundaries and PPE category reporting within a single study cycle, ArcPro links coordination outputs to arc flash boundary and PPE category reporting.
Stress-test model setup consistency for large one-line changes
For large studies, validate how each tool verifies model data consistency because EasyPower can take longer to validate due to model data consistency checks. For large models where one-line changes are frequent, confirm workflow iteration speed in CYME since boundary outcomes depend heavily on consistent equipment and operating data setup.
Confirm portability and mapping for custom equipment attributes
If custom equipment attributes drive study differences, test import mapping because Arc Flash Analytics limits projects with highly custom equipment attributes. If the workflow relies on shared model and device-setting context across coordination and hazard, confirm that the tool’s study configuration and settings management reduce boundary labeling drift across revisions.
Who fits each arc flash analysis workflow style
Arc flash hazard analysis teams usually fall into two operational profiles: engineering groups that maintain and revise network and protective device coordination models, and engineering teams that compute hazard outputs from provided fault inputs and device clearing characteristics. The tools with revision-linked mapping and coordination coupling tend to support engineering governance during study cycles.
Electrical engineering teams doing repeated study revisions from the same one-line source model
EasyPower suits repeatable boundary and PPE labeling when maintained one-line models and protective device settings must stay aligned through revision-linked report outputs.
Organizations that manage protective device coordination studies as the authoritative dataset
ETAP is a fit when incident energy outputs must remain tied to network model assumptions and device settings from the same coordination study workflow.
Engineering groups that need export-ready documentation tied to revision assumptions
Arc Flash Analytics supports repeatable studies with revision-linked boundary results and export-ready outputs that keep equipment assumptions and results traceable.
Power system model maintainers who want hazard outputs derived from in-model protection behavior
PowerFactory fits teams already maintaining power system models because it derives incident energy from the short-circuit and protection study workflow used to compute clearing behavior.
Teams that run hazard calculations from bolted fault inputs plus device clearing characteristics
ECalPro Arc Flash Hazard Calculator fits workflows where direct computation from bolted fault inputs and protective device clearing characteristics is preferred over external model exchange.
Common arc flash analysis selection and deployment pitfalls
Arc flash hazard analysis fails in predictable ways when revision traceability is weak, when model coupling assumptions are not validated, or when equipment data completeness does not match how the tool computes incident energy and boundary results. The mistakes below map to the specific workflow dependencies seen across these tools.
Selecting a tool that computes hazard outputs from protection studies without validating how it maps equipment grounding and device settings
EasyPower results depend on complete equipment grounding and protective device settings, so missing grounding or incomplete protective inputs can break boundary accuracy. ETAP and SKM Power*Tools also rely on model quality, so device-setting discipline is necessary to avoid boundary labeling drift.
Treating arc flash outputs as interchangeable across coordination revisions without enforcing revision traceability
Arc Flash Analytics reduces loss of assumptions between iterations through revision-linked studies, but importing mapping limits can cause traceability gaps when equipment attributes are highly custom. EasyPower and ETAP keep hazard outputs linked to the same coordination or protection study behavior, which reduces reconciliation effort during revisions.
Assuming faster iteration is automatic for large feeder one-line revisions
CYME workflow slows when iterating many one-line changes across large feeder models because boundary outcomes depend heavily on consistent equipment and operating data setup. Validate iteration throughput by running a representative feeder update cycle in SKM Power*Tools for Windows and in CYME using the organization’s typical revision volume.
Using direct-input calculators while the organization’s process requires model-linked studies
ECalPro Arc Flash Hazard Calculator directly computes incident energy and arc flash boundary from bolted fault inputs and protective device clearing characteristics, but it provides limited guidance beyond single calculation and reporting. When incident energy must stay tied to maintained network model assumptions across revisions, ETAP or PowerFactory better align with the existing study workflow.
Picking a coordination-linked study tool but underestimating workflow setup mapping between equipment data and study zones
ArcPro requires careful mapping between equipment data and study zones, so mismatches can misalign boundary results with the intended PPE category outputs. SKM Power*Tools for Windows can also require careful working point setup mapping to one-line equipment and buses.
How We Selected and Ranked These Tools
We evaluated how each tool keeps arc flash boundary and incident energy at working distance results linked to the same protective context used for clearing time and trip behavior. Features account for 40% of the ranking, ease and workflow iteration account for 30% total, and value account for the remaining 30% total with study revision overhead driving differences.
EasyPower separated from the pack by mapping revision-linked arc flash report changes back to specific equipment and device settings, and by producing arc flash boundary outputs that support multiple approach distances for NFPA 70E labeling. EasyPower also showed higher feature and ease scores than other revision-mapping competitors, which supported higher overall and higher value scoring in this category.
