Power Systems Expertise You Can Trust
From concept to commissioning — we deliver precise, code-compliant power systems engineering for industrial and commercial clients.
Comprehensive analytical studies to ensure safe, reliable, and code-compliant power distribution systems.
Design, specifications, and procurement of custom switchgear and switchboards through trusted OEM manufacturers.
Precise relay coordination and settings calculations to maximize system protection and minimize unnecessary interruptions.
Independent peer review of engineering designs and power systems studies for accuracy, completeness, and code compliance.
We perform the full spectrum of power systems studies required for industrial and commercial distribution systems.
Steady-state power flow studies to determine voltage profiles, loading levels, and system losses across the distribution network.
Fault current calculations (3Ø, L-L, L-G) for equipment rating verification and protective device selection per ANSI/IEEE standards.
Incident energy calculations and PPE requirements in full compliance with NFPA 70E and IEEE 1584 standards for worker safety.
Time-current curve (TCC) analysis to ensure proper selectivity and minimize fault isolation zones throughout the system.
Thermal analysis of cable systems including derating factors for conduit fill, ambient temperature, and installation method per NEC and CYMCAP.
Substation and facility grounding system design and analysis using WinIGS for ground potential rise (GPR) and step/touch voltage compliance.
