Megger UHF PD Detector 
 
Overview 
�  Non-invasive tool for online PD measurements in MV and HV substations
�  Large colour touch-screen for easy operation
�  Dual channel system for direct comparison between two sensors
�  Synchronises with power frequency via internal, mains or external sensor for PRPD pattern recognition
 
The UHF PD Detector is the ideal tool for quick, non-invasive surveys in MV and HV substations and should be part of
the toolbox for all maintenance and service teams. Thanks to high bandwidth, UHF measurements can accurately measure
local online PD activity in frequencies above those of common disturbances. In addition, the high bandwidth together
with PRPD (phase resolved partial discharge) pattern display, can categories the different types of defect. Corona
discharges and surface discharges can be easily distinguished from the dangerous internal partial discharges, which is another
advantage of this type of technology.
