COMTRADE Viewer is an easy-to-use tool for viewing and analyzing power system event records. Display waveforms directly on your device. Now includes incremental based double-ended fault locator based on method of Kasztenny and Smelich. Supported file formats include: • COMTRADE (ASCII and Binary) • SEL .cev, .eve, and .evzip event records • SEL Motor Start Reports (.msr and .cmsr) • Beckwith M-3425A, M-3430, and M-3311A .osc records • S&C IntelliRupter Fault Interrupter records (.wfc) • ATP/EMTP .pl4 files Open files directly from Mail, Files, AirDrop, and other supported apps, or explore the included sample records to get started. Built for power system engineers and technicians who need quick access to event records while in the field, at the office, or on the go.

The iOSComtradeViewer is a professional analysis tool for viewing and evaluating COMTRADE files (disturbance records) on iPhone and iPad. The app allows users to import COMTRADE files and visualize recorded data for detailed fault and event analysis. In the waveform view, all analog and binary signals are displayed over time, enabling precise inspection of Analog values and status signals. For advanced analysis, users can switch to a vector view, where phasors are displayed along the time axis, allowing detailed examination of vector behavior during disturbances and transient events. The iOSComtradeViewer is optimized for mobile use, providing fast access to disturbance records directly in the field or during commissioning and service work. Compatible with iOS and iPadOS 17.8 and later.
