AFCI offline kit - Part 9: Raw Lorraine AC arc recordings 2/3 (carbonized path, C3)
Offline development kit for an arc-fault detection / electrical-fire prevention system (current sensor -> STM32F407 ADC+DMA -> FFT/STFT features -> quantized DNN -> trip). Target offline PC: Windows 10/11 x64, CPU-only Python training.
Contents: raw Lorraine AC arc recordings (2/3): carbonized path, C3
Folder Zenodo5501527_carbonized_path_C3/: 13 C3_*_carbonizedpath.dat recordings (same appliances as Part 8).
About this dataset (Parts 8, 9, 10)
Raw series AC arc-fault recordings, 230 V / 50 Hz, Université de Lorraine (with Huaqiao Univ. / UNIVPM). Each .dat file is one long recording of current/voltage for one appliance with a series arc created either through a carbonized path (pre-carbonized cable) or an opening contact. See the ReadMe PDFs (ReadMe_Zenodo5501527.pdf in Part 8, ReadMe_Zenodo3997337.pdf in Part 10) for the binary format, sampling rate, channel meaning (C2/C3 prefixes) and the arc/normal timing.
The same lab's pre-cut windows + code (Ferracuti et al. 2025) are in Part 7 — use those first; use these raw files when you want to choose your own window length / sampling rate (e.g. to match what the STM32F407 ADC can actually sample).

Rebuilding split files
Files over 100 MB were split into *.part001, *.part002, ... pieces. After downloading the whole repo:
- Windows:
powershell -ExecutionPolicy Bypass -File .\join_parts.ps1 - Linux/macOS:
bash join_parts.sh
Both scripts rebuild the files and check them against SHA256SUMS.txt.
