4.4.3.
TF flexible current sensors
The TF flexible current sensors use the Rogowski principle, covering a wide current range without saturation.
Their flexible design and easy opening system enables a quick installation inside electrical panels, making them particularly
well suited for adding measuring points in existing electrical installations, especially when space is limited.
The secure lock technology prevents non voluntary openings of the Rogowski rope. Thanks to the specific link, they are
recognised by the DIRIS B-10L and a high level of overall accuracy for the measurement chain is guaranteed.
4.4.3.1. Range
Six models are available, covering a large current range up to 6000 A with openings of different shapes and sizes. They
include a compact and self-supplied integrator, required to shape the current signal.
