The Universal Viewer is a specialized, high-resolution graphic interface designed for management, display and analysis of fault and periodic load files from various types of proprietary & standard formats generated from DFRs, Digital Relays, Meters and more. The software supports the latest IEEE long file naming format (C37.232).

The advanced analyis interface offers a wide range of flexible analysis tools for navigating traces, peak hopping, amplitude and time scaling, superimposing, peak detecting, RMS and phase calculating, instantaneous values, primary and secondary values, sequence components, triggers, envelopes, merge files, append files and time synchronization of multiple records.

Computed Software Channels are also provided for advanced analysis. Software Channels can be used to compute + , - and 0 Sequence, Resistance, Envelopes, Missing Phases, Convert to Primary or Secondary Values, Current Imbalances, % of Rating...
