High Voltage Installation, Testing, and Maintenance
Serving Raleigh & Surrounding Areas
Comprehensive High Voltage Solutions
Design-Build, Modernization, and Lifecycle Support
G3 Electric delivers end-to-end high voltage services, from new medium-voltage distribution installs to modernization of aging infrastructure. Our scope covers utility coordination, primary metering, padmount and dry-type transformers, switchgear and switchboards, MV cable pulling and terminations, busway, grounding systems, and protective relaying. We execute turnkey projects that integrate generators, UPS, and transfer schemes, ensuring resilience and uptime.
Whether you need a service upgrade, campus distribution loop, or substation additions, we handle feasibility, budgeting, and construction with a single accountable team. Our engineers perform load studies, short-circuit and coordination analyses, and arc flash studies to optimize protection settings and selective coordination. The result is a safe, efficient high voltage system engineered for your present loads and future expansion.
Standards-Driven Workflows and Documentation
Safety is built into every phase. We adhere to NFPA 70E, OSHA, NEC, and manufacturer specifications, and implement rigorous lockout/tagout, energized work permitting, and job hazard analysis. Acceptance and maintenance testing are performed to NETA ATS/MTS standards, including insulation resistance, VLF/hipot for MV cables, primary and secondary injection of breakers and relays, ground grid testing, thermography, and power quality measurements to validate performance before energization.
Quality assurance continues through commissioning with point-to-point verification, torque and term checks, and functional testing of control schemes. You receive updated single-line diagrams, labeling and arc flash equipment labels per IEEE 1584, maintenance plans, and as-built documentation. We provide owner training, warranty support, and periodic testing schedules to keep systems compliant and reliable throughout their lifecycle.
Tailored Service for Every Stakeholder
For realtors and property management teams, G3 Electric provides rapid due diligence and operational assessments of electrical systems, including infrared scans, capacity verification, code compliance punch lists, and remediation plans. We prioritize clear reporting, predictable scheduling, and minimal disruption to tenants, enabling confident transactions and smooth turnovers.
For residential and commercial contractors, we offer design-assist and value engineering, BIM coordination, prefabrication-ready submittals, and sequence-driven work plans that de-risk schedules. Our team executes service upgrades, temporary power strategies, switchgear packages, MV cable terminations, and full commissioning support, aligning protection settings and documentation with closeout requirements.
For homeowners and HOA stakeholders overseeing estates, private wells or lift stations, and long-run site lighting, we deliver safe step-down transformer solutions, surge protection, and backup power integration that interface with medium-voltage distribution. We emphasize transparent pricing, bonded and insured crews, and 24/7 response to protect critical loads and keep properties operating safely.
