High Voltage Design, Installation, and Maintenance

Serving Little Elm & Surrounding Areas

End-to-End High Voltage Solutions

Safe, code-compliant design and construction

From concept to energization, we engineer and build medium- and high-voltage systems that meet rigorous performance and safety standards. Our capabilities include primary distribution (5kV–38kV+), utility services, pad-mounted and unit substations, primary metering, switchgear lineups, SCADA integration, protective relaying, grounding grid design, and detailed protective device coordination and arc‑flash studies. We align every project with NEC/NFPA 70, NFPA 70E, NESC, IEEE, and utility interconnection requirements to ensure long-term reliability and compliance.

Construction is executed by qualified high-voltage technicians and electricians with proven methods for excavation, duct banks, vaults/manholes, precision cable pulling, splicing, and terminations. We perform NETA-accepted testing such as insulation resistance, VLF/hipot, power factor, and relay verification, followed by labeling, one-line updates, and comprehensive O&M documentation for a smooth turnover.

Reliability programs that cut downtime

We implement preventive and predictive maintenance programs tailored to your equipment and risk profile. Services include infrared thermography, ultrasonic and partial discharge surveys, breaker primary injection and timing, relay calibration, transformer DGA and oil quality testing, insulation resistance and power factor testing, cleaning and lubrication, and load studies. Our technicians schedule work around your operations to minimize outages and optimize system health.

Safety drives every task: lockout/tagout, energized work permitting, approach boundaries, and arc-rated PPE are standard. When issues arise, our team provides 24/7 emergency response for fault location, cable repairs, temporary power, and switchgear remediation. We also deliver power quality analysis and mitigation to address harmonics, voltage sags/swells, and transient events.

From greenfield to energized turnover

Whether expanding capacity or building new, we manage preconstruction, estimating, value engineering, and utility coordination to de-risk schedules and budgets. Our team designs and installs feeders, duct banks, manholes, primary metering, and indoor/outdoor switchgear, with BIM coordination, constructability reviews, and material logistics to accelerate delivery.

Commissioning is structured with ITPs, FAT/SAT, NETA ATS/MTS acceptance testing, energization plans, and contingency procedures. We verify protections, interlocks, SCADA points, labeling, and grounding performance, providing redlines, as-builts, arc‑flash and coordination study reports, and training so your staff is ready on day one.

For clarity, Low Voltage refers to systems such as security cameras, access control, and network cabling. While those technologies are distinct, our focus here is on the medium/high-voltage infrastructure that safely powers your facility and supports those downstream systems.
