USENS-B

USENS-B

CAPTEUR DE DÉCHARGE PARTIELLE UHF.

CARACTÉRISTIQUES PRINCIPALES

  • Conception robuste, installation facile sur la barrière SIG
  • Diélectrique élevé et protection intégrée contre les surtensions
  • Capteur UHF haute sensibilité et large bande
  • Blindé pour éviter l’interface électromagnétique
  • Classé IP66, adapté à l’environnement extérieur de la sous-station
  • Personnalisé pour s’adapter à toutes les tailles d’ouvertures de barrière

Highly sensitive, reliable, 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
