The COMTRADE Viewer includes a fault data manager and a graphical analysis interface. The data manager supports the IEEE Standard C37.232-2011 "File Naming Convention for Time Sequence Data" (COMNAME). The analysis interface supports IEEE Standard C37.111-1991/1999/2013 "Common Format for Transient Data Exchange" (COMTRADE).

It provides fast sort and query engines, smart copy, move, and delete methods, and it allows for appending and merging of multiple records. The product is loaded with analysis features including waveform plots, phasor diagrams, sequence of events reports, harmonic tables, software channels, circular charts, and is equipped with an array of calculators for calculating frequency, sequence components, and fault location (both single and double ended algorithms are provided).

Universal Viewer

The Universal Viewer is an advanced version of the COMTRADE Viewer. It includes drivers for reading proprietary formats from various IED producers. It includes a universal converter for converting the proprietary formats to COMTRADE (both ASCII and Binary formats are supported). It provides macros for creating inputs to short circuit simulation and modeling applications.

It is also equipped with expert system modules for ranking fault records (based on targets, magnitude, and duration), and for trending periodic load measurements over long periods of time (based on overload, imbalance, and efficiency). The product is recognized for its effectiveness in simplifying and expediting the process of fault and disturbance analysis and was sighted by NERC as being "indispensable" in the blackout investigation of August 14th, 2003.

Device Manager

The Device Manager is an advanced version of the Universal Viewer. It includes an extensive library of drivers for polling IEDs and retrieving their latest fault and disturbance records. It provides a database for configuring communication, storage, and reporting parameters. It complies with NERC PRC and CIP requirements.

Each copy can poll up to 2,000 devices simultaneously. Both "report by exception" and "poll upon demand" functionality are supported and reports on communications integrity are also provided. The product is used for logging access and changing passwords on numerical relays and is equipped with an HMI used to populate single line diagrams with periodic readings including volts, amps, watts, VARs and status information.

COMTRADE Conformity Check (CCC)

COMTRADE Conformity Check is designed to detect format errors in COMTRADE files. These errors which can be almost impossible to spot with the naked eye have made anaylsis harder for protection engineers for years. With over 80 possible errors in the CFG and DAT file combined if there is an error CCC will catch it.

CCC supports all three active versions of the Comtrade standard, 1991, 1999, and 2013 without the user having to specify anything other than the filename. The user simply chooses a directory they would like the report files saved to, and the filename. Once the Create Report button is clicked the Application does the rest.

Wavewin Data Diode

The Wavewin Data Diode is used to collect fault and disturbance data files from various types of CCA devices within an ESP (such as numerical relays), and then securly moves the collected data to a second Wavewin Diode outside the ESP.

The collected data files include digital fault records, sequence of events records, metering logs, device settings, and health checks.
