Model 3002 SER System

The Model 3002 SER System is a state of the art data collection and analysis system. It is suitable for application in an electrical utility substation or plant environment to produce Sequence of Event (SER) data in conformance with PRC-002-1 and PRC-018-1.

The Model 3002 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.

This model can be expanded at any time to include analog input channels, converting it into the Model 2002.

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 SER computer so analysis can be performed at the substation.
