Power System Studies & ETAP Modeling:
- Short-Circuit & Load Flow Analysis: Evaluating available fault currents, equipment interrupting ratings, and transformer/cable loading profiles across AC and DC systems.
- Protection Relay Coordination (ETAP Star): Time-overcurrent protection reviews, sequence-of-operation verification, and relay selectivity studies to isolate faults without system-wide blackouts.
- Arc Flash Hazard & Safety Analysis: Quantifying incident energy levels, determining safe boundary distances, and producing NFPA 70E / IEEE 1584 compliant warning labels.
- Harmonics & Power Quality Assessments: Identifying harmonics, voltage sags/swells, and power factor deficits with custom mitigation (passive/active harmonic filters).
- Motor Starting & Transient Stability Studies: Dynamic simulation of large motor starts to prevent voltage collapse and ensure network resilience.
Electrical Testing & Field Diagnostics:
- Root Cause Failure Analysis (RCFA): In-depth investigations into chronic electrical trips, transformer anomalies, and switchgear failures.
- Substation & Switchgear Testing: Primary/secondary injection testing, insulation resistance testing (Megger/Hi-Pot), and contact resistance checks.
- Industrial Electronics & PCB Diagnostics: Specialized component-level troubleshooting, repair, and reprogramming for critical drive cards and industrial controller boards.
- Engineering Training & Competency Development: Custom training modules covering electrical troubleshooting, protective relay coordination, and safety compliance.
