Diagram types
Display records from digital protection units and fault recorders in six diagram types: time-signal, vector, circle, bar charts and data tables. Measure fault traces with two synchronized cursors for detailed analysis.
Why SIGRA?
SIGRA is a fault record evaluation tool that displays and measures records from digital protection units and fault recorders. Quickly analyze line faults to derive proper measures, restore original line conditions and reduce downtime.
Display records in various views and calculate values like impedances and symmetrical components. Understand fault causes and determine precise fault locations to save time during on-site inspections. Visualize complex data with six diagram types, including time signal, vector and fault locator views. Use two measurement cursors for fault trace evaluation. Add and synchronize multiple fault records for a complete picture to restore operations faster and more efficiently.
Key benefits
Analyze fault lines quickly
Fully analyze line faults to immediately derive proper measures from the cause evaluation. Understand fault origins with precision for effective response.
Reduce downtime
Quickly restore original line conditions and limit downtime. Minimize operational disruptions and enable rapid recovery of your electrical systems for sustained performance.
Accelerate repairs
Speed up repairs during on-site inspections and improve overall system availability. Determine fault locations precisely with the offline fault localization feature.
Featured capabilities
all
Electrical value calculation and analysis
Calculate additional values from recorded fault data, including absent quantities in three-wire systems, impedances, outputs and symmetrical components. Gain deeper insights into system behavior for comprehensive fault analysis.
all
Record combination and synchronization
Add and synchronize multiple fault records to a common time base, including signals from opposite ends of a line, using drag and drop. Display various fault records in a single diagram for integrated analysis and comparison.
