Transformer Temperature Monitoring System

Overloading, aging, and poor cable contact can cause a transformer to overheat, often resulting in a fire disaster. As a result, a temperature monitoring system is the ideal solution to mitigate and prevent such disasters.

The Senkox TDS-TR Temperature Monitoring System offers unparalleled versatility, accuracy, and functionality in managing transformer fire safety. The Senkox HSD Linear Heat Sensors (LHS) can be placed on the surface of the transformer and provide real-time monitoring of any temperature changes. In addition, the system will locate the position and size of the emerging hot spot. The Senkox HSD LHS cables are flexible, resistant to fatigue, and can be used to cover any span of the desired monitored area.

The TDS-TR system is composed of multiple Senkox HSD Linear Hot Spot Detectors and accessories; the HSD Linear Hot Spot Detector includes HSD linear heat sensors and DAQ modules.
