UHF-50/80 Drain Valve Sensor

 

The UHF-50 or UHF-80 are UHF drain valve sensors used for the decoupling of PD signals from the inside of oil-immersed components in power transformers. Versions are available for standard DN 50 and DN 80 drain valves. Leak-free installation of the sensor is done quickly and easily and the PD signals can be analyzed with the HTP-2/UHF PD Detector or PDMS DAQ PD Monitoring System.

Features:

  • Easy and leak-free installation on oil-filled transformers and reactors
  • UHF-50 and UHF-80 versions available for standard DN 50 and DN 80 drain valves
  • Online installation of the sensor, no power-down necessary
  • Suitable for temporary measurements as well as permanent installation for continuous on-line monitoring
  • Performs UHF signal measurements with transformer tank acting as natural shield against external interferences
  • Wide frequency range 100 MHz - 2 GHz
