Our High Voltage Process
Planning & Safety
High voltage work starts with a detailed safety plan, job hazard analysis, and coordination with the utility. We don't rush high voltage.
Utility Coordination
We coordinate shutdowns, switching orders, and safety grounding with LG&E or your utility provider.
Installation
Our qualified high voltage electricians install, terminate, and connect medium/high voltage equipment following NFPA 70E safety procedures.
Testing & Energization
We perform cable testing, phase rotation checks, and protective relay verification before energization. Safety first, always.
High Voltage Cost Factors
High voltage work carries premium costs due to specialized requirements:
- Voltage level and system complexity
- Length and size of medium voltage cable runs
- Transformer size and specifications
- Utility coordination requirements and fees
- Safety equipment and specialized tooling
- Scheduled vs. emergency outage windows
High Voltage Electrical FAQs
What voltage levels do you work with?
We work with systems from 480V up through 15kV (15,000 volts). This covers most industrial and commercial medium voltage applications including motor drives, transformers, and distribution systems.
Do you coordinate with LG&E?
Yes. We handle all coordination with Louisville Gas & Electric for service upgrades, transformer installations, and metering changes. We manage the utility paperwork and scheduling.
Is high voltage work safe?
It is when done by qualified electricians following proper safety protocols. Our team follows NFPA 70E procedures including safety grounding, personal protective equipment, energized work permits, and lockout/tagout. Our Gold Standard Step Award for safety demonstrates our commitment.
Can you test high voltage cables?
Yes. We perform hipot (high potential) testing, VLF (very low frequency) testing, and insulation resistance testing on medium voltage cables to verify integrity before energization.
