high performance PD sensors:

UHF Spiral antenna is a partial discharge sensor designed to receive electromagnetic (EM) emissions from a PD occurring in the monitored asset. It is a broadband antenna with a flat response which makes Spiral antenna suitable in a number of different applications. It has been optimized to operate in a frequency range typical for PD activity and it was designed to provide maximum sensitivity and high gain.

  • Power Transformer


  • Compact
  • Robust design (passive sensor)
  • Optimal sensor for direct installaton on high voltage Transformer


Its compact and robust design (passive sensor) makes Spiral antenna the optimal sensor for direct installation on Power-Transformers equipped with dielectric windows.
