Model 2002 DME system

Multifunction data collection and analysis system

The Model 2002 is the highly successful predecessor to the Model 9000. It continues to be a best-in-the-class all-in-one system for customers who maintain large fleets of existing 2002 DME systems.

Computer, Software, and web-based graphic user interface

The Model 2002 uses, as the DME Master Station, an industrial-grade fanless computer running Windows Embedded Standard 7 (WES7) as its operating system. This combination provides highly reliable operation and low maintenance cost. The standard Fault Location feature automatically determines information such as faulted line, fault type, duration, and distance to fault which are displayed at the recorder and can be automatically transferred to the Master Station or to SCADA via DNP3. The USIMaster (DAS)© application is included in the purchase of each DME system and runs on any computer running Windows 95 through Server 2012 operating system. The master station analysis software is also loaded on the DME computer so fault analysis can be performed at the substation.
