Summation current sensor (splittable)
The summation current sensor (splittable) from HORSTMANN is a sensor for earth fault detection in medium-voltage networks. The product is listed as splittable and is intended for use with Sigma D+, Sigma D++ and the ComPass B-series. The summation current sensor (splittable) measures residual currents by being placed around all three-phase conductors, enabling high-precision detection of very low earth fault currents.
Function and features
- Splittable design (can be installed without interrupting wiring).
- Designed to detect residual currents by placing the sensor around all three phase conductors.
- Supports precise detection of very low earth fault currents.
- Compatible with Sigma D+, Sigma D++, and the ComPass B-series.
Typical applications
The summation current sensor (splittable) is used for earth fault detection in medium-voltage networks, especially in RESPE networks (resonant earthing with voltage limitation). In combination with a directional fault indicator like Sigma D+, the sensor can contribute to selective fault localization independent of neutral point treatment.
