Whether delivering electricity generated with solar power in the desert to the coast of the British Isles or electricity from offshore wind farms in the North Sea to the Alps – renewable energy needs to cover long distances so that green electricity can be made available everywhere. Thousands of kilometres of new routes for subsea and underground cables are required for this energy transition. This means that thousands of kilometres of cables need to be tested, monitored and maintained to ensure that they operate reliably. With the technology previously available this was not possible.

For high voltage direct current (HVDC) transmission cables, which are for example used to transport electricity from wind farms in the north to industrial locations in the south, HIGHVOLT has developed a new system called HiMON® to monitor the status of the lines. With the aid of state-of-the-art sensors and artificial intelligence, it can detect problems immediately, accurately locate them and determine potential sources of faults early on.
