USENS-V

USENS-V

UHF PARTIAL DISCHARGE SENSOR.

KEY FEATURES

  • Wide band, Highly Sensitive, UHF PD Sensors for Transformer Drain Valves
  • High Dielectric, Rugged, and Reliable design
  • Built-in overvoltage (transient) protection
  • Shielded to avoid electromagnetic interface
  • 100% Leak proof and pressure tested for 10 bar

Highly sensitive and accurate Partial Discharge sensor for measuring ultra high frequency signals emitted by partial discharge activity inside Transformers. 

USENS-V is an Ultra High Frequency (UHF) antenna that can detect smallest UHF frequencies emitted by the partial discharge (PD) activity. The sensors are suitable for all types of Transformers, and easy installation on the transformer drain valves. The IP65 rated ingress protection allows sensor to be installed at Outdoor installations. Their wide band (200 – 2000 MHz) frequency response and high sensitivity (up to -90dBm) enables lower cost of PD monitoring system and higher ROI (Return on Investment).
