## What is iOSComtradeViewer?

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.
