Services
Electrical Distribution Testing
Our electrical distribution testing ensures optimal performance of substations and industrial systems through NETA and IEEE-compliant diagnostics. We identify potential failures in transformers, circuit breakers, and switchgear using advanced tools like infrared scanning and partial discharge analysis. This proactive approach minimizes downtime while extending equipment lifespan for utility and industrial clients.
Protective Relay Programming
We specialize in programming and testing electromechanical, solid-state, and digital protective relays to enhance system reliability. Our engineers implement precise settings for fault detection and isolation, ensuring compliance with coordination studies. This service prevents cascading failures and maintains operational continuity in high-voltage environments.
Arc Flash Studies
Our arc flash studies assess electrical hazards to create safer work environments. By analyzing fault currents and protective device timing, we determine incident energy levels and recommend PPE requirements. This service helps clients meet OSHA and NFPA 70E compliance while protecting personnel from electrical risks.
Substation Maintenance
We deliver comprehensive substation maintenance programs including preventive inspections, oil testing, and equipment retrofits. Our technicians address corona damage, contact wear, and insulation degradation to ensure long-term reliability. Regular maintenance reduces unplanned outages and extends the lifecycle of critical power infrastructure.
Transformer Testing
Our transformer testing services include power factor analysis, winding resistance measurements, and oil dielectric testing to evaluate equipment health. We perform internal inspections and oil degassing to detect early signs of insulation breakdown. These diagnostics ensure transformers operate efficiently under load while preventing catastrophic failures.
