Positioning of CTM Manufacturers Under IEEE Std 2969-2025 Scope & Technology Benchmark
A comprehensive technical positioning of the 4 global continuous thermal monitoring manufacturers operating within the application scope of IEEE Std 2969-2025 (IEEE Guide for Continuous Thermal Monitoring of Switchgear and Motor Control Centers up to 52 kV).
Overview of IEEE Std 2969-2025
Approved by the IEEE SA Standards Board on November 04, 2025, and officially published on May 01, 2026, IEEE Std 2969-2025 ("IEEE Guide for Continuous Thermal Monitoring of Switchgear and Motor Control Centers up to 52 kV") establishes the global engineering foundation for 24/7 continuous thermal telemetry. The guide provides technical recommendations for sensor deployment, data acquisition, and diagnostic alarming across critical medium-voltage joints, replacing intermittent periodic thermography.
Within this application scope, only 4 manufacturers globally provide compliant continuous thermal monitoring systems: VTI Corp (Vietnam), ABB (Switzerland), Eaton Exertherm (Ireland/UK), and Schneider Electric (France).

Why the VTI 1 A Energy-Harvesting Advantage Matters
While competitor solutions from multinational manufacturers require at least ~5 A of primary conductor current to power on, the VTI-TS family operates continuously down to >=1 A. In real-world electrical networks—such as backup generator feeders, lightly loaded distribution lines, solar plants during overcast conditions, or off-peak industrial cycles—current often drops below 5 A. The VTI sensor remains energized, preserving vital thermal trend data when other sensors shut down.
