Model 2002

The Model 2002 DME System is a state of the art, multifunction data collection and analysis system. It is suitable for application in an electrical utility substation or plant environment to produce Sequence of Event (SER), Digital Fault Recorder (DFR), Dynamic Disturbance Recorder (DDR), and Continuous Recorder data in conformance with PRC-002-1 and PRC-018-1. All data recorded by the DME system is stored in IEEE C37.111 format and named in conformance with IEEE C37.232. The system also has a software option to enable the Phasor Measurement Unit (PMU) feature to provide streaming data in conformance with IEEE C37.118.

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.
