USENS-B

USENS-B

UHF PARTIAL DISCHARGE SENSOR.

KEY FEATURES

  • Rugged Design, Easy installation on the GIS Barrier
  • High Dielectric and Built-in overvoltage protection
  • Highly Sensitivity, and Wide band UHF PD Sensor
  • Shielded to avoid electromagnetic interface
  • IP66 rated, suitable for outdoor substation environment
  • Customized to fit any size of barrier openings

Highly sensitivereliable, UHF technology based Partial Discharge sensors for GIS barrier openings. 

USENS-B is an Ultra High Frequency (UHF) antenna that can detect smallest UHF frequencies emitted by the partial discharge (PD) activity. The sensors are customized to fit on different kind of GIS barrier openings. 
The sensors can easily be placed on the barrier opening and then fixed with the belt (optional) around the barrier. Their wider frequency response and higher sensitivity ensures higher GIS coverage for PD monitoring. 

  • Periodic partial discharge testing and measurements
  • Continuous online partial discharge monitoring
  • High voltage testing after maintenance/ overhaul
  • GIS/ GIL PD Testing and Monitoring
  • GIT (Gas Insulated Transformers) PD Testing & Monitoring
  • Circuit Breaker PD Testing and Monitoring
  • Higher sensitivity (-70dBm) ensure higher ROI of monitoring
  • Wide frequency response, compatible with all PDM systems
  • Easy installable, and High Dielectric strength, Safest Sensors
  • Shielded Sensor, Noise Immunity
  • Built-in overvoltage protection keeps the PDM electronics safer
  • IP65 protection and rugged design, suitable for outdoor installations
  • Leak proof sensors enables safety and 0% SF6 leakage
  • Customized according to Barrier Opening and customer requirements
