Luxtron® ThermAsset2

LuxtronThermAsset2

Effective Fiber Optic Hot Spot Monitor and Controller for Power Transformers

The Luxtron® ThermAsset®2 controller is designed to measure transformer winding hot spots in real-time and activate control of the cooling system. This allows for optimum transformer operation at safe load capacity during overload conditions.

The ThermAsset2 controller offers many of the reliable and proven features considered the standard for fiber optic temperature measurement of transformer windings in the power utility industry. The same-patented Fluoroptic® thermometer (FOT) technology is employed using a lifetime LED light source to activate the sensors. The ThermAsset2 utilises Luxtron® ruggedized probes, the toughest in the industry, which require no calibration over the lifetime of the transformer.
