How do you know it worked? Launch ETAP and perform these three quick tests:
| Issue | Solution |
|--------|----------|
| No module named etap | ETAP is not a pip library; use COM interface |
| CreateObject failed | Run Python as Admin; ensure ETAP is installed and licensed |
| API connection refused | Enable ETAP API in ETAP options → API Server |
Installing an ETAP engineering library is typically integrated into the main software installation, but you can also manually link, update, or customize library files (.lib) within the application. General Installation & Setup
During a standard ETAP installation, the engineering device library is automatically included and placed in a default directory (often C:\ETAP [Version]).
Administrator Rights: You must have administrative privileges to install ETAP and its libraries.
Security Settings: It is recommended to turn off User Account Control (UAC) and the Firewall during installation to prevent errors.
Exclusion List: ETAP's installer automatically adds the engineering device library (.lib) to the Windows Defender Exclusion List to improve project performance. How to Link or Open a Library in ETAP
If you need to use a specific library file for your project: Open your project in ETAP. Go to the Library menu and select Open.
Navigate to the directory containing your .lib file, select it, and click Open.
The library is now attached to your project, allowing you to select verified devices for your single-line diagrams. Managing Library Files
ETAP provides several tools to manage and customize these data sets:
Library File Management: You can Create, Save As, Merge, or Purge library files via the Engineering Libraries module. etap library install
Smart Merge: This feature allows you to merge specific models or sizes from one library into another without overwriting the entire file.
Version Preservation: If an existing library (e.g., ETAPLIB.lib) is found during a new installation, ETAP typically renames it to ETAPLIB.bak to preserve your previous data. Customizing Library Data
You can add specific equipment data (like cables or relays) not found in the standard library:
Add New Data: Access the library, click Add, and input manufacturer-specific properties such as ampacity, impedance, and physical characteristics.
Mapping Files: For external integrations like SmartPlant Electrical, you can import or build Mapping XML files to sync library data between platforms.
For detailed step-by-step visuals, you may refer to the ETAP 19 Install Guide or the Quick Installation Guide.

The cursor on Sarah’s screen blinked, a tiny, rhythmic mockery of her progress. It was 8:00 PM on a Tuesday, and she was stuck in the middle of a, quite frankly, urgent power system study for a new, massive industrial client.
She needed the exact manufacturer data for a 13.8kV circuit breaker, but her current ETAP project was showing a glaring, empty space in the protective device library. "ETAP Library install," she muttered, opening the ETAP Help Center
documentation. It wasn't the first time she’d done this, but it was always a nerve-wracking process. Libraries were the backbone of accurate simulation; get it wrong, and the arc flash analysis would be useless. How do you know it worked
She closed the main project, her breath catching as she opened the Library Management tool. She had downloaded the latest update file from the ETAP User Portal
earlier that afternoon, a file promising thousands of new devices from manufacturers like Siemens, ABB, and Schneider Electric. 1. Open ETAP Library Manager. 2. Select "Update Library." 3. Locate the downloaded library file. She followed the steps, watching the progress bar.
Since I cannot find a widely recognized mainstream library named exactly "etap" in the standard Python (PyPI) or JavaScript (NPM) registries, I have drafted a flexible review template.
It is possible you are referring to:
Below is a comprehensive review draft. You can fill in the bracketed sections [like this] to customize it for the specific tool you are using.
[Etap] is a solid choice for developers working on [specific niche] projects who don't mind getting their hands dirty with the source code. However, if you require robust enterprise support or comprehensive documentation, you might want to wait for a more mature release.
Suggested Action for Maintainers: Focus on expanding the API reference and creating a troubleshooting guide for the installation errors common on [OS].
Create etap.lock. This file records the exact commit hash or version downloaded to ensure the exact same binary is built on CI/CD servers.
If you could provide more context or specifics about the ETAP library you're trying to install, I'd be more than happy to give you a tailored answer.
To "install" or update an ETAP library, you typically perform a Copy/Merge
operation. This allows you to integrate new manufacturer data (from a | Issue | Solution | |--------|----------| | No
file) into your existing project library without losing your current settings. 1. Preparation Locate your library: By default, ETAP libraries are found in the folder of your installation directory (e.g., C:\ETAP [Version]\Lib Always save a backup copy of your existing file before merging to prevent data loss. Permissions: You must log in to the project as a to perform merge operations. 2. Steps to Merge/Install a New Library
Follow these steps to add data from a new source library (e.g., an update from the ETAP Help Center or a manufacturer like LS Electric Open Project:
Launch your ETAP project and ensure the current library is loaded via Access Merge Tool: Go to the top menu and select Copy/Merge Select Source & Destination: One field should show your project library In the second field, click the button to browse and select the you want to "install". Set Direction: Arrow button between the two library paths to point the new source library your project library. Connect Project: Check the box labeled "Connect library to the merged library" to ensure your project immediately uses the updated file.
. A summary window will appear showing which devices (e.g., circuit breakers, cables, relays) are being merged. Click again to finish. 3. Adding Specific Data Manually
If you only need to add a single component (like a specific cable), you can do so manually: Navigate to the specific library (e.g.,
and enter data from the manufacturer's datasheet (impedance, ampacity, physical dimensions). 4. Updating from the Web

To install the ETAP library, you would typically follow a series of steps depending on your environment and how you intend to use ETAP. ETAP (Electrical Transient and Analysis Program) is a comprehensive software tool used for power system transient and dynamic analysis. It's widely used in the field of electrical engineering for designing and analyzing power systems.
import comtypes.clienttry: etap = comtypes.client.GetActiveObject("ETAP.Application") except: etap = comtypes.client.CreateObject("ETAP.Application")
etap.Visible = True project = etap.ActiveProject print(project.Name)
As of 2026, there is no official etap library on PyPI.
If you see references to pip install etap, it’s either:
You can search:
pip search etap # (deprecated) or use pip index
