Wavewin - Waveform Data/COMTRADE Viewer & Analysis Tools 

Wavewin  is used for fast line restoration, post-fault and disturbance analysis, dynamic relay testing, real time monitoring of evolving loads, contingency planning, and intelligent maintenance applications.
Thanks to the powerful math on the recorded voltage and current signals, Wavewin is able to calculate the fault location and the fault resistance, giving valuable information to the relay engineer on how to optimize the relay settings with the experience gained by the transient recording of the power system faults.
The software is a specialized, high-resolution graphic interface designed for universal management, display and analysis of digital fault records.
Wavewin supports IEC 60255-24 / IEEE Std. C37.111 COMTRADE format (known also as COMTRADE 2013) and any previous COMTRADE format (1991 and 1999). It can of course open any format and save/convert in any format.  Standard CSV format is also supported (which also allows for trending of periodic load measurements over long periods of time).
Wavewin supports additionally a long and growing list of proprietary disturbance recorder file formats.

Wavewin - COMTRADE Viewer 

The Comtrade Viewer includes a fault data manager and a graphical analysis interface. The data manager supports the IEC 60255-24 / IEEE Standard C37.232-2011 “File Naming Convention for Time Sequence Data” (COMNAME). The analysis interface supports EC 60255-24 / IEEE Std. C37.111-1991/1999/2013 “Common Format for Transient Data Exchange” (COMTRADE). The product is recognized for its effectiveness in reading various implementations of the COMTRADE standard from various producers of intelligent electronic devices (IEDs) such as numerical relays, digital fault recorders, and disturbance monitors. The product is also recognized for its capability of handling and managing large volumes of COMTRADE records. 
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). 


Wavewin - 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.

Wavewin - COMTRADE Conformity Check

The 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 67 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.
