Global fault window
ViewerInception and clearance cursors in the waveform viewer now span all channels and propagate to the fault location, distance, and overcurrent tabs. Drag a cursor to apply globally, delete to revert to auto-detection. Override values persist across reload and sign-out.
Waveform viewer docsDifferential relay registry
DifferentialSeven relay families now supported with a registry-driven preset editor. Select a relay model to auto-populate characteristic parameters. Includes bias method selection (dual-slope, through-fault, variable percentage) and trip signal detection with T badges on the characteristic chart.
Differential protection docsFault location: X1 reactance input
Fault LocationNew X1/angle impedance input mode for the fault location tab, alongside the existing R/X and Z/angle options. Useful when relay settings are expressed in reactance-only form.
Fault location docsFault location: 5-algorithm engine
Fault LocationComplete overhaul with Takagi, Modified Takagi, Eriksson, Novosel, and Radial algorithms running in parallel. Supports all k₀ formats (SEL, ABB, Siemens, Schneider), R/X and Z/angle impedance inputs, source impedance settings, and a redesigned UI with a hero banner and per-algorithm result pills.
Fault location docsCurrent-augmented fault classification
AIFault type detection now uses current phasors alongside voltage for more accurate classification. A dual-source detection algorithm handles cases where voltage depression alone is ambiguous.
Fault analysis docsCursor context menu and time reference
ViewerRight-click any cursor to open a context menu. Pin a time reference to zero-anchor timestamps — useful for aligning fault events across channels. The reference propagates across all tabs.

Sharing docsHarmonics DFT accuracy
HarmonicsRemoved the Hanning window from the harmonics DFT and fixed endpoint double-counting. Results are now more accurate for steady-state power quality analysis.
