Since QElectroTech is an open-source application for creating electrical diagrams, using a "Portable" version is a great way to keep your projects and symbols on a USB drive or a cloud folder without needing administrative rights to install it. 1. Getting the Portable Version
QElectroTech doesn't always have a single "Portable.exe" file, but it is distributed as a ready-to-run ZIP archive for Windows or an AppImage for Linux.
Windows: Go to the official download page and look for the Windows 64-bit (ZIP) version.
Linux: Download the AppImage file. This is a single file that runs without installation; just right-click it, go to Properties, and "Allow executing file as program." 2. Setup and "Portability" Mode
To ensure the app stays truly portable (saving settings and symbols in its own folder rather than your computer's AppData), follow these steps:
Extract the ZIP: Unzip the contents into a folder on your USB drive (e.g., D:\QET_Portable\).
Create a 'conf' folder: Inside the main QElectroTech folder (where qelectrotech.exe lives), create a new folder named conf.
Note: Many portable builds look for this folder to store your configuration and custom symbols locally. Run the App: Double-click qelectrotech.exe. 3. Managing Your Portable Libraries
One of the best parts of QET is the symbol library. To keep it portable:
User Symbols: Store any custom symbols you download or create inside a subfolder in your portable directory.

The thumb drive was nondescript: matte black, a faded “32GB” sticker, and a tiny scratch shaped like a crescent moon. To anyone else, it was e-waste. To Mira, it was a skeleton key.
She plugged it into the industrial terminal at the decommissioned substation, ignoring the warning tape fluttering in the damp wind. The old Windows 7 machine wheezed to life. She navigated to the drive’s root folder and clicked the green icon labeled QElectroTech_Portable.exe.
The software opened with a clean, almost cheerful grid. No installation. No registry keys left behind. Just pure, unadulterated schematic capture.
Mira was a ghost in the grid—an independent systems auditor for decaying infrastructure. Her clients paid her to find failures before they caused blackouts. But tonight, she wasn’t auditing. She was building.
On the left panel of QElectroTech, she dragged components onto the canvas: a contactor coil, a set of normally open auxiliary contacts, a thermal overload relay. Her fingers flew across the laptop’s sticky keyboard, wiring them together with the software’s automatic routing. Each click was a silent vow.
The original schematics for this substation had been “lost” in a server migration three years ago. The new management company claimed everything was up to code. But Mira had felt the heat stain on a cable tray during her daytime walkthrough—a whisper of resistance where there shouldn’t be any.
Using the portable app, she began reverse-engineering the dead circuit. QElectroTech wasn't flashy like AutoCAD or EPLAN. It was a scalpel, not a laser. It let her label conductors with cryptic tags like K201/A2 and F101/14. She built a ladder logic diagram from scratch, rung by rung, her breath fogging the screen.
Then she found it.
A hidden bypass relay. Someone had jumpered a safety interlock using a discarded piece of 14-gauge wire and buried it behind a false panel. The original engineer had probably done it to keep production running one rainy Tuesday, swearing he’d fix it later. Later never came.
Now, that bypass meant the main breaker wouldn’t trip if a phase lost power. It would just sit there, silently overheating, until the busbar melted and rained molten copper onto the control room below.
Mira saved her work: Substation_7_Actual_v2.qet. She didn't overwrite the corrupted official file. Instead, she exported the diagram as a PDF and a PNG, tucking copies into encrypted folders on the thumb drive. Then, using QElectroTech’s native “print to scale” function, she sent one copy to the substation’s rickety thermal printer.
The dot matrix screeched awake, chattering in the dark. Line by line, coil by contact, the truth emerged on fanfold paper.
She tore off the printout, taped it to the inside of the breaker cabinet door, and whispered to the humming relays, “Fixed.”
Then she unplugged the drive. No history. No temp files. QElectroTech Portable had left no trace on the host machine—just a clean, correct schematic in the hands of the night shift electrician who would find it at sunrise.
Outside, the first streetlight flickered, held, and stayed steady.
Mira smiled. The ghost had done her work. you plug in
