RelaySec-FEL: Relay Secondary-Circuit Fault Element Localization Dataset

RelaySec-FEL is a field-format experimental dataset for element-level fault localization in relay-protection secondary circuits. It supports ranking candidate fault elements from incomplete, noisy, delayed, and conflicting multi-source evidence.This Zenodo record freezes release version 1.0.0 as the archive RelaySec-FEL-v1.0.0.zip. The archive contains 20,000 diagnostic cases, static-structure tables, dynamic-evidence tables, labels, maintenance-verification tables, and derived static-graph files.This is constructed experimental data, not production operational data. Station names, asset identifiers, addresses, records, and timestamps are experimental items. Labels and maintenance outcomes are intended only for supervised training and evaluation, not inference-time feature construction.Mutable distribution repository: https://huggingface.co/datasets/james12221/RelaySec-FEL
