Transformers are the backbone of any power distribution system. Whether installed in utility substations, industrial plants, or commercial campuses, these units enable efficient voltage regulation and safe power delivery across your facility. However, like any critical equipment, transformers require expert servicing to ensure reliability, safety, and long-term performance.
At MidStates Energy, we provide full-spectrum transformer services—designed to minimize downtime, extend equipment lifespan, and keep your operations compliant and efficient. From routine maintenance and diagnostics to urgent repairs and replacements, our team delivers transformer solutions tailored to your site’s unique power infrastructure.
Why Transformer Maintenance Is Essential
Transformers operate under extreme conditions—high voltage, high load demand, and fluctuating temperatures. Without routine inspections and proper care, they can experience degradation, leading to power interruptions, equipment damage, and significant repair costs.
Common transformer issues include:
- Insulation breakdown due to moisture, heat, or contamination
- Oil degradation and reduced dielectric strength
- Bushing wear, leaks, or partial discharge
- Malfunctioning tap changers or winding shifts
- Cooling system failures
- Corrosion and seal damage from environmental exposure
Preventive transformer maintenance helps avoid these problems by detecting early warning signs and correcting small issues before they escalate into system-wide failures.
MidStates Energy’s Transformer Service Solutions
We offer a comprehensive suite of services to protect, test, and optimize transformers across industries and power capacities. Our technicians are experienced with all major transformer types, including dry-type, oil-filled, pad-mounted, pole-mounted, and substation units.
1. Preventive Maintenance & Visual Inspection
Our team performs structured inspections of all external components, checking for rust, cracks, fluid leaks, overheating signs, or mechanical wear. We also inspect surrounding infrastructure and ground connections to ensure system integrity.
2. Oil Sampling and Analysis
Transformer oil acts as both an insulator and coolant. Over time, it can degrade or become contaminated. We perform laboratory-grade oil testing to assess moisture levels, dielectric strength, and gas concentrations—providing an accurate view of transformer health.
3. Thermal Imaging and Infrared Diagnostics
Thermal scans help detect hot spots, loose connections, or load imbalances without interrupting service. These non-invasive tests identify areas of concern early and allow for targeted maintenance.
4. Bushing & Tap Changer Services
We inspect and service bushings, replacing degraded units as needed, and ensure that tap changers are calibrated and functioning within spec. Improper tap changer operation is a major cause of transformer inefficiency and overheating.
5. Leak Repair and Gasket Replacement
Oil or gas leaks threaten both performance and environmental compliance. Our technicians locate and repair leaks, replace worn gaskets and seals, and verify that your transformer is fully sealed and safe to operate.
6. Emergency Repairs and Mobile Response
When a transformer fails, time is of the essence. MidStates Energy offers 24/7 rapid-response services to assess, repair, or temporarily replace critical components. We bring mobile oil processing, testing equipment, and experienced technicians directly to your site.
7. Installation & Commissioning
MidStates Energy provides end-to-end transformer installation services. From rigging and mounting to wiring, testing, and energization, we ensure every installation meets industry standards and performs flawlessly from day one.

Transformer FAQs
1. How often should my transformer be serviced?
We recommend transformer maintenance and oil testing every 12–24 months, depending on environmental exposure, load demands, and transformer age. Mission-critical systems may require quarterly reviews.
2. What does transformer oil analysis detect?
Oil analysis provides insight into internal conditions—measuring dielectric strength, dissolved gases (like hydrogen or carbon monoxide), moisture content, and particulate contamination. These indicators help identify early-stage electrical or thermal faults.
3. Can MidStates Energy service energized transformers?
Yes. We offer non-invasive testing like thermal imaging and oil sampling while the transformer is live. For repairs, we coordinate planned outages to minimize disruption.
4. Do you work with all transformer brands and sizes?
Absolutely. MidStates Energy services a wide range of transformer makes and models, including those by ABB, Siemens, GE, Eaton, and more—covering both distribution and high-voltage systems.
