Gas Insulated Systems (GIS) have attained a very high degree of reliability and availability. Nevertheless, failures cannot totally be excluded, as shown by service experience. Besides manufacturing, defects may be induced by aging, in the course of time. Such defects shall be found as early as possible, in any case before an outage is caused.

Typical sources for PD in GIS are:

  • Protrusions
  • Particles fixed to an insulator surface
  • Free moving particles
  • Electrically floating parts


Techimp provides complete solutions for GIS, representing the utmost state of the art of the technology commercially available. Techimp Technology for GIS consists of a PD monitoring unit and UHF Sensors with accessories covering all the possible ranges of applications  and PD measurements in GIS.


Partial discharge (PD) measurement using UHF sensors is the most common technology used to diagnose conditions of insulation in Gas Insulated System (GIS). 
Techimp provides a complete range of sensors for PD analysis in GIS with accessories, developed and optimized for best sensitivity and maximum flexibility.
