Current monitoring of earth cables is always a major challenge for grid operators, as standard current sensors cannot be installed. Converting the three-conductor terminations to single-conductor plastic cables is complex and expensive. Thanks to Horstmann’s new technologies, however, it has been possible to develop an innovative sensor concept that solves precisely this problem. The new CSOR earth cable current sensor enables reliable current monitoring – even with insulated and unshielded earth cables. As a result, the digitalization of local network stations can be further advanced regardless of the medium-voltage cable used.

Advantages of the new sensor solutions:
✅ Safety thanks to type-tested retrofitting options
✅ Cost savings thanks to compact and simple installation
✅ Time efficiency thanks to quick installation
✅ Flexibility for all standard earth cables
✅ Universal applicability for all ComPass and Sigma devices

These developments represent significant progress on the way to a smart energy supply. They show that even existing infrastructures can benefit from modern technology. Let’s shape the future of medium-voltage technology together!
