Cabletroll
Cabletroll 2350
The Cabletroll 2330 is a fault current detector engineered for medium-voltage underground distribution networks operating within a voltage range of 6–36 kV. Designed for reliable, precise fault detection using standard 500:1 current transformers (CTs). CTs can be supplied with the fault indicator, or existing CTs can be used.
- Short Circuit (SC) & Earth Faults (EF) detections
- Separat indication for EF and SC
- Signalling contacts for SCADA integration
