Built for Protection Engineers
Inspect analog and digital records, place timing cursors, review phasors and sequence components, and export engineering output from a browser-based workspace.
Used for disturbance review, relay behavior checks, training cases, and report-ready event analysis.
Analysis Previews
Use these previews to see measured review, timing cursors, and coordinated analysis in motion.
Load CFG + DAT disturbance records in the browser and move immediately to waveform inspection, zoom, pan, and cursor-based review.
Measure harmonic spectrum, THD, RMS, phase angle, and order-by-order content directly from COMTRADE current and voltage records.
Review positive-, negative-, and zero-sequence quantities with phasor-based insight for faster fault interpretation and relay behavior checks.
Correlate analog change, digital trips, breaker status, and timing markers on a shared axis, then export engineering evidence for reports and handoff.
Measured Review
A practical disturbance review workspace must support measured timing, relay-oriented interpretation, and exportable engineering output.
Derive positive-, negative-, and zero-sequence quantities to support fault interpretation and phase-balance review.
Inspect fundamental behavior, harmonic content, and waveform distortion to support analysis of transients, saturation effects, and signal quality.
Correlate analog behavior with digital status changes on a common time base for trip, pickup, and auxiliary contact review.
Engineering Output
Review is only part of the job. The output also needs to be clear, traceable, and easy to share. Export the same measured record into engineering-ready formats for internal review, client delivery, training material, or case documentation.
Professional Identity
This workspace fits teams and specialists who need a faster, more consistent way to review COMTRADE records and produce traceable engineering output.
Use a consistent review workflow for disturbance analysis, timing checks, and internal engineering documentation
Work from the browser when client environments restrict installs, while keeping measured outputs and report export in one place.
Use real or synthetic COMTRADE cases to teach relay behavior, timing relationships, and analytical method.
Access and Pricing
Free access covers record inspection and first-pass waveform review. Paid access starts when the work becomes measurable, exportable, and ready for engineering handoff.
