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

Fault Root-Cause Analysis

Systematically organize relay dumps, sequence-of-events data, and field observations to identify permanent vs. transient fault origins

Protection Relay Coordination Verification

Cross-reference observed relay operations against protection settings to detect coordination failures or nuisance trips

Diagnostic Hypothesis Generation

Produce ranked fault scenarios with supporting evidence from SCADA data, voltage/current waveforms, and protection responses

Outage Impact Assessment

Estimate economic impact, identify cascading failure risks, and prioritize restoration sequencing

Equipment Anomaly Flagging

Highlight suspicious patterns in relay behavior, timing discrepancies, or settings mismatches requiring specialist review

Forensic Documentation Support

Generate structured outage summaries suitable for stakeholder reports and regulatory filings

Pre-Fault-Season Auditing

Systematically review historical fault patterns and protection settings to identify recurrent issues before peak seasons

Example Output

Example 1: Line Trip Investigation

code
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

code
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

What's Included

  • SKILL.md: Core system prompt for structured fault analysis workflows
  • Fault Analysis Template: Structured worksheet for organizing relay data, SCADA logs, field reports, and evidence chains
  • Protection Coordination Checklist: Verification framework mapping relay operation sequences against settings and time-current curves
  • Outage Forensics Framework: Guided narrative structure for root-cause reports, impact assessment, and remediation recommendations
  • Historical Pattern Audit Tool: Checklist for reviewing fault trends, protection anomalies, and setting drift over seasonal cycles
