Preventive and Predictive Maintenance
Transformers are long-term assets that require consistent upkeep to operate safely and efficiently. Our customized maintenance programs are designed around your facility’s operational requirements, environmental conditions, and energy demands. Services include thorough visual inspections to identify early signs of wear, corrosion, or overheating; oil sampling and dissolved gas analysis to detect potential internal issues; thermal imaging to locate overheating components before they fail; insulation, turns ratio, and contact resistance testing for performance verification; and customized maintenance schedules aligned with your facility’s load and conditions. By taking a proactive approach, we reduce the risk of costly failures, minimize downtime, and maximize transformer lifespan.
Advanced Diagnostic Testing
Early detection of hidden transformer issues is critical to preventing unplanned outages. MidStates Energy uses advanced diagnostic technologies to assess transformer performance and identify potential problems before they impact operations. Our testing capabilities include power factor analysis to evaluate insulation quality and dielectric integrity, sweep frequency response analysis to detect core or winding displacement, insulation resistance testing to confirm operational reliability under stress, bushing and load tap changer testing for voltage stability, and partial discharge detection to locate insulation weaknesses without interrupting service. After every assessment, we provide a detailed report with actionable recommendations to ensure peak performance.
Repairs, Upgrades, and Component Overhauls
MidStates Energy provides complete repair and modernization services to extend transformer life and enhance system reliability. We perform load tap changer replacements and refurbishments, cooling system upgrades with advanced fan and pump retrofits, bushing and gasket replacements to eliminate leaks and contamination, core and winding repairs to improve energy efficiency, and integration of Beckwith and SEL controllers for enhanced monitoring and automation. Upgrading your transformer components ensures your systems remain compliant, efficient, and capable of supporting future energy demands.
Transformer Installation and Commissioning
Our team provides turnkey transformer installation and commissioning services, managing every step from initial planning to energization. We handle site preparation, equipment rigging and secure placement, bushing assembly, vacuum filling, and oil processing for oil-filled transformers, high-voltage insulation testing, and final system verification prior to startup. After installation, we perform complete commissioning procedures, including energization and performance reporting, to ensure seamless integration into your facility’s electrical infrastructure.
