Temperature measurement applications

  • EHV/UHV/HVDC Transformers
  • Power Transformers
  • Distribution Transformers
  • Reactors, Generators
  • Load Tap Changers
  • Switchgear
  • Power Cables

Power transformers often take the brunt of an overload condition, and are the most likely to be damaged without proper control and protection.
WEIDMANN InsuLogix® T thermal monitor is designed to measure transformer winding hot spots in real time. The drift-free, calibration-free and maintenance-free InsuLogix® T allows for optimum operation of the transformer at safe load
capacity during normal and emergency conditions. The temperature measurement is based on proven Gallium Arsenide sensor. The sensor possesses a resilient construction and has dielectric materials featuring complete immunity to EMI and RFI environments. The fiber optic cable is specially designed for permanent installation in a liquid immersed transformer. Unlike conventional top oil temperature measurements which can lag hours behind in response time, fiber optics
provide direct, real-time accurate measurements of the transformer winding temperature, suitable for dynamic load control or as a valuable input to calibrate thermal models.

The InsuLogix® T system, including WEIDMANN Certified SmartSpacer®, is the most comprehensive system in the market for winding hot spot measurements and protection and control of transformer auxiliary systems.
