Transmission System Fault Analysis Assistant
Diagnose transmission faults and analyze protection relay data rapidly
What You Can Do
You can rapidly diagnose root causes of transmission line faults by organizing relay data, SCADA logs, and field reports into coherent analytical narratives. Claude helps you verify protective device coordination, identify protection scheme failures, and rank remediation priorities by risk level. This accelerates outage forensics, supports stakeholder reporting, and flags equipment anomalies that warrant immediate investigation.
Features
Systematically organize relay dumps, sequence-of-events data, and field observations to identify permanent vs. transient fault origins
Cross-reference observed relay operations against protection settings to detect coordination failures or nuisance trips
Produce ranked fault scenarios with supporting evidence from SCADA data, voltage/current waveforms, and protection responses
Estimate economic impact, identify cascading failure risks, and prioritize restoration sequencing
Highlight suspicious patterns in relay behavior, timing discrepancies, or settings mismatches requiring specialist review
Generate structured outage summaries suitable for stakeholder reports and regulatory filings
Systematically review historical fault patterns and protection settings to identify recurrent issues before peak seasons
Example Output
Example 1: Line Trip Investigation
Fault Event: 230 kV Line A trip
Relay Data Provided: Phase relay timings, distance relay zones, breaker operation logs
Analysis Output:
• Primary hypothesis: Permanent phase-to-ground fault at 45 km, downstream of line midpoint
• Supporting evidence: Zone 2 pickup timing matches calculated impedance; neutral displacement voltage surge at Station B
• Protection coordination verified: Primary relay (Zone 1) failed to clear; backup relay (Zone 2) operated within tolerance
• Risk flags: Breaker pole-slip detected on phase C — recommend mechanical inspection
• Recommendation: Inspect line for insulator damage 40–50 km from Station A; test breaker synchronization
Example 2: Nuisance Trip Analysis
Fault Event: Three transient trips in 72 hours, no sustained fault
Data: Instantaneous settings, transient waveforms, load flow during trip times
Analysis Output:
• Hypothesis: Capacitor bank switching transients triggering relay sensitivity drift
• Evidence: Trip timestamps correlate with reactive power swings; relay operates 15% below nominal threshold
• Coordination issue: Setting margin eroded; adjacent protection may fail to backup under sustained fault
• Recommendation: Recalibrate relay (pickup > 1.2× max transient current); install transient suppression on capacitor circuit
