ProEdison Launches ProWave, a Free COMTRADE Viewer

MOUNT SINAI, N.Y. - EntSun -- ProEdison LLC today announced the release of ProWave™, a free COMTRADE viewer and modern waveform fault analysis tool built specifically for protection and control engineers. ProWave reads IEEE C37.111 COMTRADE records (1999/2013, ASCII and binary) generated by protection relays, giving engineering teams a single, consistent environment to analyze power system faults regardless of relay manufacturer.

Protection groups have long depended on a patchwork of aging, vendor-specific utilities to open and analyze fault records. ProWave replaces that fragmented toolchain with one standardized analysis environment, decoupling waveform analysis from relay procurement so teams keep the same workflow even as their hardware changes.

Key Features of ProWave™

ProWave delivers a comprehensive set of capabilities for modern fault analysis:

• Universal COMTRADE compatibility — Reads C37.111 records (1999/2013, ASCII and binary).
• Vendor-independent analysis — Decouples your waveform analysis process from relay procurement.
• Repeatable, auditable workflows — Standardized event handling across the protection group means less variance and more defensible post-event reports.
• Consistent analysis methodology — The same cursors, markers, timers, phasors, and harmonics on every COMTRADE waveform record.
• Multi-tab COMTRADE comparisons — Open and compare multiple fault records side by side in a single workspace.
• Multi-channel signal and timing alignment — View analog current, analog voltage, and digital signals in separate panes with synchronized T0, T1, and T2 marker overlays.
• Phasor and vector analysis — Phasor and harmonic plots open alongside the waveform.
• Modern UI/UX — A fluid, contemporary interface designed to streamline engineering analysis.
