Techimp HFCT is an inductive sensor for partial discharge measurements.
It is suitable for on/off line PD tests on many electrical systems (cables, transformers, rotating machine, etc..). It has to be applied to the ground connection of the system to be tested.

  • Gis
  • High Voltage Cables
  • Medium Voltage Cables
  • Medium and Low Voltage Switchgear
  • Power Transformer


  • Maintenance free
  • High sensitivity and reliability
  • Robust and easy to use
  • Safety


A BNC termination is available to connect the HFCT to the Techimp PD detection /analyzer unit through a coaxial cable. The arrow indicates the output voltage (Vout) direction in comparison with the input current (Iin) direction: when the sensor is installed with the arrow directed to ground junction, the detected voltage signal (Vout) has the same phase as the input current (Iin).
