Empowering Reliability: Dry-Type Transformer Temperature Monitoring for Data Centers & Renewables

As demand grows for resilient, energy-efficient infrastructure, dry-type transformer temperature monitoring is vital in data centers and renewable energy systems. Higher power densities and uptime requirements make real-time monitoring and control essential.

The Rise of Dry-Type Transformers in Critical Applications

Data Center Dry-Type Transformer Monitoring

Dry-type transformers with AF (Air Forced) or FA (Fan-Assisted) cooling are now standard in hyperscale and edge data centers. Data center transformer temperature monitoring ensures fire safety, compact design, and reliable thermal performance. 

Renewable Dry-Type Transformer Monitoring

Wind and solar farms face harsh environments and varying loads. Renewable dry-type transformer monitoring delivers remote visibility and robust, low-maintenance operation.

Enter the Qualitrol 118ITM: Intelligent Thermal Monitoring

The Qualitrol 118ITM is purpose-built for dry-type transformers with active cooling. Here’s how it delivers unmatched value: 

  • Real-Time Temperature Monitoring: Continuously track winding temperatures using thermocouples.
  • Fan Control Logic: Automatically activates cooling fans based on temperature thresholds, reducing manual intervention and energy waste.
  • Alarm & Trip Outputs: Protects assets by triggering alarms or shutdowns when critical limits are exceeded.
  • Modbus Communication: Seamlessly integrates with SCADA and building management systems for centralized visibility.
  • Compact, Rugged Design: Built to withstand harsh environments typical of industrial applications. 

Benefits by Application

For Data Centers

  • Zero Downtime: The 118ITM helps stop overheating before it causes problems, keeping your data center running without surprise outages. Its design even helps reduce the effects of EMI (electromagnetic interference) on thermocouple readings, so your temperature data stays accurate. 
  • Energy Efficiency: Smart fan control adjusts cooling only when needed, lowering energy use and cutting costs.
  • Built to Last: The 118ITM uses Type K thermocouples that can handle constant vibrations, changes in temperature, and mechanical stress — making them a strong choice for demanding data center environments.
  • Easy Data Integration: with Modbus and analog outputs, the 118ITM connects easily to your existing data analytics platforms, making it simple to use advanced predictive maintenance tools.
  • Compliance & Reporting: Automatically send temperature and performance data to your monitoring systems to meet industry requirements and stay audit-ready.

For Renewables

  • Remote Monitoring: Keep track of transformers in wind or solar farms from anywhere with SCADA-ready communication, so you can respond quickly to issues.
  • Tough in Any Environment: Designed to work reliably in dusty, humid, high-altitude, and coastal locations without losing performance. Its Type K thermocouples can also take on vibrations, temperature swings, and mechanical stress — perfect for the challenges of renewable sites.
  • Longer Equipment Life: Intelligent cooling reduces heat stress, helping your transformers last longer and cutting down on maintenance costs.
  • Easy Data Integration: like in data centers, the 118ITM’s Modbus and analog outputs make it easy to connect with external analytics platforms for predictive maintenance and performance tracking.
