Our Transformer Process
Load Analysis & Sizing
We calculate your facility's electrical load and growth projections to specify the right transformer size, type, and voltage configuration.
Utility Coordination
We coordinate with Louisville Gas & Electric or your utility provider on service requirements, metering, and connection specifications.
Installation
Our crews handle pad construction, transformer setting, primary and secondary connections, and all associated electrical work.
Testing & Energization
We perform insulation resistance testing, turns ratio testing, and verify all connections before coordinating energization with the utility.
Transformer Cost Factors
Transformer costs depend on several factors:
- kVA rating and voltage class
- Transformer type (pad-mount, pole-mount, dry-type, oil-filled)
- Single-phase vs. three-phase
- Indoor vs. outdoor installation
- Concrete pad and bollard requirements
- Utility connection and metering fees
- Typical range: $5,000–$50,000+ depending on size and type
Transformer Installation FAQs
How long does a transformer installation take?
A straightforward pad-mount transformer replacement typically takes 2-3 days including pad preparation, setting, connections, and testing. New installations requiring utility coordination may take 4-8 weeks total including lead times.
How long do transformers last?
Well-maintained transformers typically last 25-40 years. Signs of failure include oil leaks, unusual humming or buzzing, overheating, and inconsistent voltage output. We can test your transformer to assess its remaining useful life.
Do you handle the utility coordination?
Yes. We handle all coordination with LG&E or your utility provider, including service applications, metering requirements, and scheduling the utility's connection work.
Can you install transformers for three-phase power?
Yes. We install single-phase and three-phase transformers in all common configurations — delta-wye, wye-wye, delta-delta — based on your facility's requirements and the utility's service type.
