SAET initiated its activity in the sector of substations by supplying the protection and control panels according to the ENEL standards (later unified as ENEL DCO90 and DPT96) with the relative auxiliary AD and DC services. 


The activity of electromechanical assembly of HV equipment that led to attainment of ENEL CAA/1100 qualification represented the natural development of SAET’s activities as a service in the sector of Power Substations.

After a number of experience in the complete design of substations up to 380 kV (from the lay out of the yard to the design of the auxiliary services and systems of protection and control) SAET has been qualified as a supplier of complete turnkey substations with important contracts in Italy and abroad, with an integrated view that enables the client to deal with a single contractor for POWER, PROTECTION and CONTROL.
