Underground fault indicators
Our fault indicators for cable networks encompass a diverse range of models, each designed with distinct functionalities and detection principles.
Solutions that go even further
Our fault indicators for cable networks encompass a diverse range of models, each designed with distinct functionalities and detection principles. From basic earth fault indicators to models that detect both earth faults and short-circuit currents, we offer advanced solutions that go even further by identifying fault current direction, feeding direction, and providing the user with a detailed fault sequence analysis. This allows for post-fault investigation and aids in network maintenance planning to proactively prevent future unexpected failures.
All our cable network indicators can be equipped with a variety of communication solutions, enabling efficient transmission of fault alarms and other measurements conducted by the field units, ensuring comprehensive monitoring and rapid response capabilities.
