230 kV Lightning Performance Analysis

Led a lightning performance investigation for a 230 kV transmission line experiencing higher-than-typical lightning trip rates.

Scope included:
- Full field inspection of existing line conditions
- Updates and comparisons to engineering computer models and as-built drawings
- Shield angle analysis and optimization
- Soil resistivity testing across the line route
- Structure impedance testing
- Back-flashover analysis and tripout rate evaluation
- Remediation recommendations including proposed modifications to standard structure designs
- Deliverable package with detailed findings and recommended actions

The study provided the utility with data-driven remediation strategies specifically targeting high-lightning-activity areas along the corridor.
