4.2. Presentation of associated current sensors
Various types of current sensors can be connected to ISOM Digiware:
Fault-locating core balance transformers
• Solid-core (ΔIP)
• Split-core (ΔIP-R)
• Rectangular (WR, TFR)
Current sensors for measuring load currents
• Solid-core (TE)
• Split-core (TR) or exible (TF).
The difference between these sensors means they can be adapted to any type of new, existing or high-current
existing installation. They all use a specic link with the fault-locating module ISOM Digiware F-60. This link provides a
quick connection, with no cabling errors. ISOM Digiware recognises the sensor size and type. In addition, combining
them means the overall accuracy of ISOMDigiware + current sensor measurement chain can be guaranteed over a
large measurement range.

Important:
To connect the current sensors, use only SOCOMEC cables, RJ12 straight cables, twisted pair, unshielded, 600V,
-10°C / +70°C as per IEC 61010-1 version 3.0. We recommend that all the current sensors are installed in the same
direction.
Connection cables for current sensors:
* When laying cables, do not exceed a maximum length of 10 metres.
