An introduction to Detego and how to use it for power system fault analysis.
Detego is a browser-based fault analysis platform designed for power protection engineers. It allows you to upload, visualize, and analyze power system disturbance recordings in the COMTRADE (IEEE C37.111) format — the industry standard for storing oscillographic data from protective relays and fault recorders.
The platform combines interactive waveform visualization with a comprehensive compute engine and AI-powered analysis to help engineers quickly understand fault events, verify relay performance, and document findings.
Create substations and devices that mirror your physical network. Import relay settings from XRIO files to pre-populate distance zones, overcurrent curves, CT/VT ratios, and more.
Device Management GuideDrop files to upload
Drop COMTRADE files (.cfg + .dat or .cff) into the viewer or the recordings page. Detego parses the data instantly in your browser and saves it to your library.
Recordings GuideVisualize waveforms, compute derived quantities — phasors, sequence components, impedance, harmonics, power, directional assessment — and explore the data across interactive tabs.
Waveform Viewer GuideLet the AI engine analyze the recording end-to-end. It reads the computed quantities, queries relay manuals, and produces a structured fault report with verdict, classification, and protection assessment.
AI Analysis GuideCompose a structured engineering report by hand. Add waveform snapshots, phasor diagrams, measurement tables, event timelines, and narrative text. Export to PDF with your branding.
