Functional Competencies

- Protection Relays: Programming, testing, and parameterization of numerical relays using automated kits (Omicron/Megger).
- HV Diagnostics: Primary/secondary testing, breaker timing,



tan delta, IR/PI, and DGA for generators, transformers, and 220kV switchyards.
- Fault Analysis & SAS: Evaluating Disturbance Recorder logs/oscillograms for trip root causes; configuring IEC 61850 protocol and GOOSE messaging.
- System Design: Relay coordination, setting calculations, CT/VT sizing, and interlock/breaker failure scheme verification.

Behavioral & Management Competencies:

- Decision Making: Analyzes trip logs (DR/SER) without rushing unsafe re-energization.
- Safety Rigor & Courage: Enforces strict LOTO/PTW protocols; asserts technical holds when equipment fails insulation tests.
- Analytical Precision: Meticulous with relay setting calculations and CT/VT ratios.
- Outage Execution: Manages tight testing schedules during overhauls.
- Incident Investigation: Leads Root Cause Analysis (RCA) for unit trips.
