Automated IED Data Analysis

DFR Assistant™ product family offers over 10 years of practical application of automated analysis of substation data collected by digital fault recorders (DFRs). Substation Assistant™ builds on the DFR Assistant™ technology and includes automated analysis of substation data recorded by digital protective relays, circuit breaker recorders and other IEDs that provide event recording.

Automated Analysis

• Identifies monitored circuit with highest disturbance.
• Determines fault type performs accurate fault location calculation.
• Saves time by sorting substation event data by priority.
• Provides customized protective relay operation evaluation.

Comprehensive Reports

• Provides customized implementation that matches specific user needs.
• Enables easy retrieval of data and reports by time, location, event characteristics, etc.
• Represents one-stop solution for viewing field data, system configuration, and analysis reports.
• Allows merging analysis reports with waveform analysis.

Combined Functions

• Allows use of both data and analysis reports by other enterprise applications.
• Enables two-end fault location calculation to use data from single-end analysis function.
• Reduces maintenance cost by accessing both analysis tools and data via corporate network.
• Combines interfaces for protection staff, maintenance crews and system operators.
