HFCT Clamp
Clamp High Frequency Current Transformer Ø 39 - 78 -140mm
High performance inductive PD sensors
TECHIMP’s Clamp High Frequency Current Transformer are inductive sensors for partial discharge measurements. It is suitable for on/off line PD tests on many electrical systems such as cables, transformers, rotating machine, etc…
The main advantage of a Clamp HFCT is that it can be clamped directly on the ground connection of the system to be tested without deenergizing it.
OVERVIEW
Benefits
- Maintenance free
- High sensitivity and reliability
- Robust and easy to use
- Safety
A coaxial TNC connector is available to connect the Clamp HFCT to the PD acquisition unit through a suitable 50Ω coaxial cable. The arrow indicates the direction of the output voltage (Vout) in comparison with the direction of the input current (Iin): 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).
