EN.SURE is LIOS’ continuous and cost-effective monitoring solution of the electric power transmission and distribution grid and is the key factor for a successful Smart Grid implementation.
Following a global trend also our customers in the USA are expanding their commitment to ensuring the reliability and performance of the transmission and distribution systems they operate. LIOS EN.SURE supports that commitment and is the flexible solution for underground high voltage cables, overhead transmission lines and submarine cables as well as for array cables within on and offshore wind farm installations.
Please find below some examples of recent EN.SURE installations in North America.
