Temperature Protection Relay (TPR)

Description: STM32G0 microcontroller-based Temperature Protection Relay  (TPR) measures transformer winding temperature with the help of Resistance Temperature Detector (RTD). It provides protection to the motor from over-temperature and insufficient ventilation or cooling. This device is equipped with a 4-channel winding temperature measurement and customized user programmable alarm. Moreover, it is suitable for operations in transformers and other machine types. It has the capability to identify short circuits and breakage inside the circuit sensors. Along with this the inbuilt alarm indication, trip & fan control gives effective solutions.

  • 4 channel temperature measurement
  • Accuracy (+/- 2 degrees)
  • Range (0 to 200 degrees)
  • Trip & Alarm (User programmable)
