Three Steps
From raw COMTRADE data to a full fault report. No installs, no hassle.
Drag and drop .cfg + .dat or .cff files to begin. Your COMTRADE recording loads straight into the viewer.
Interactive waveforms, phasor diagrams, harmonics, impedance, and symmetrical components, all in one view.
Protection analysis, power quantities, and AI-written fault reports, derived from the recording you just uploaded.
Features
One COMTRADE recording. Every phasor, every signal, every report.
Analog and digital channels with zoom, cursors, and RMS overlay. Annotations, computed signals, and flexible subplot layouts, driven by interactive Plotly.js charts.
Thirteen dedicated tabs for the way you actually analyze a fault. Waveforms, phasors, harmonics, impedance, power, differential, distance, directional, overcurrent, fault location, readout, and an AI-written report.
Work locally, or save recordings and analyses to the cloud. Search, filter, organize in folders, revisit anytime. Generate shareable links to send fault reports to colleagues instantly.
Compose a structured engineering report by hand. Drag in waveform snapshots, measurement tables, impedance diagrams, and narrative text. Arrange, annotate, and export.
Prefer an instant first draft? The AI reads the computed quantities, consults the relay manual, and delivers a structured fault report. Currently in early access.
Under the Hood
Every number on the page traces back to the samples you uploaded. No black boxes.
.cfg + .dat or .cff into structured channels, exactly per IEEE C37.111.
Full-cycle DFT · magnitude, angle, sequence components, RMS, impedance.
Distance, differential, directional, overcurrent, and fault-location methods.
The AI references the computed quantities and produces a structured fault report.
