high performance inductive PD sensors:
High Frequency Current Transformer Clamp Ø 30-50-70-90 mm
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.

High sensitivity and reliability
Robust and easy to use
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).
