Cable monitoring

Cable infrastructures for direct current grids are becoming increasingly important for the energy transition. Every laid cable requires good insulation to prevent energy losses or electric shocks. In high-power DC grids, micro-faults in the insulation can grow and promote the damage process of a cable.

WITT Solutions GmbH provides different monitoring systems for the various tasks.

Especially for charging stations for trains, buses, lorries or for the operation of a DC railway. In this application, the cables are usually laid in trenches and shafts or in cable installation shafts to transmit the energy. Many variables, such as transport or installation, can damage the cable, causing tiny cracks to form in the sheath and allowing moisture to penetrate. Particularly in the case of direct current with high power, micro-faults can grow in the insulation and thus further favour the damage process. It is therefore essential that the power cable is monitored in addition to its actual use. It is not just a matter of recognising that a cable is damaged, but ideally also where and at what point or how severe the damage is. Particularly in the case of return conductors in copper railway earthing, the theft of cable systems is also a special task. WITT Solutions GmbH provides various monitoring systems for different tasks. From simple insulation monitoring of the cable to complex measurement tasks to localise the position of the fault or influence.
