UHF-50 / UHF-80 Drain Valve PD 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.
