Requirements and application of UHF PD monitoring systems for gas insulated systems

In the TB, the hardware and software requirements of modern ultra-high frequency (UHF) partial discharge monitoring (PDM) systems for gas insulated substations/lines are determined. It is based on abundant collected knowledge from the field combined with understanding the expectations and needs of GIS end-users. Its purpose is to provide comprehensive technical guidance to help users choose a PDM system best fitting their real needs and their level of PD knowledge. Ideally, a PDM system should reliably detect, monitor, and interpret the signals from incipient PD defects, so that asset managers can take prompt and appropriate actions to prevent equipment malfunction. This TB provides guidance for more effective use of PDM systems for GIS.

Materials and emerging test techniques

This Technical Brochure has been created by a Working Group from the CIGRE Materials and emerging test techniques Study Committee which is one of CIGRE's 16 domains of work.
The scope of Study Committee D1 covers new and existing materials for electrotechnology, diagnostic techniques and related knowledge rules, as well as emerging test techniques with expected impact on power systems in the medium to long term.
