Transformer monitoring solutions and safety devices for new and retrofit projects
The U.S. electric grid is facing increasing challenges driven by rising electricity demand, aging infrastructure, climate‑related stress, and the rapid growth of high‑load applications such as data centers. Under these conditions, transformer reliability is critical for both new installations and existing substations.
A large portion of the North American transformer fleet is approaching the end of its design life. Asset refurbishment, retrofitting, targeted upgrades, and new transformer projects are essential to maintaining grid reliability, operational safety, and service continuity.
Transformer solutions compliant with ANSI/IEEE standards
Power transformers are core assets of the electrical system, particularly in continuous and high‑load applications such as utility networks and data centers, where uptime and thermal performance are key operational requirements. New and retrofit transformers, together with their accessories and monitoring systems, must comply with ANSI/IEEE standards defining performance, safety, and testing requirements.
COMEM Group provides integrated transformer solutions combining monitoring, safety devices, and services to enhance operational reliability, protect critical assets, and support efficient maintenance across a wide range of installations. The offering includes service and consulting, diagnostics and maintenance support, and asset health reporting, enabling informed asset‑management decisions throughout the transformer lifecycle.
At the core of this approach is MeDICA, COMEM’s modular asset health management ecosystem, providing a vendor‑agnostic platform for transformer monitoring and diagnostics.
Products supporting monitoring, protection, and retrofit projects
To support these solutions, the COMEM portfolio for the North American market includes ANSI/IEEE‑compliant products addressing key operational and maintenance functions:
- Breathers for moisture ingress prevention and insulation protection
- Dissolved Gas Analyzers (DGA) for early fault detection
- Fiber-optic temperature monitoring systems for direct hot-spot measurement
- Non-condenser dry-type bushings for demanding environments
- Pressure relief devices for overpressure protection
- Protection relays for fault detection and transformer safety
- Measurement and indication gauges for local supervision of key parameters
COMEM solutions are designed to be compatible with multiple transformer brands and interchangeable with equivalent third‑party models, supporting retrofit and replacement projects while reducing engineering effort and minimizing downtime. They are engineered for demanding environments, including offshore and marine installations, seismic regions, digitally monitored substations, and mission‑critical infrastructure such as data centers.
