Techimp HFCT, Clamp 39mm.

Techimp High Frequency Current Transformer 39mm Clamp is an inductive sensor for Partial Discharge detection.
It is suitable for on/off line PD tests on many electrical systems such as cables, transformers, rotating machine, etc...

The main advantage of the HFCT 39mm Clamp is the easy installation on the ground connection of the electrical system under test without the need of disconnecting it.

A coaxial BNC connector is available to connect the HFCT 39mm Clamp to any Techimp PD acquisition unit by means of a 50 Ohm coaxial cable.

The arrow on the enclosure indicates the polarity of the output voltage (Vout) in relation to the input current (Iin) direction: when the sensor is installed with the arrow directed to ground, the detected voltage signal (Vout) has the same phase as the input current (Iin).
