Technical Area. A technical area will be located in the position shown in the project tables which will contain: - The MT frame, containing the overall MT device (DG); - The protection of the transformer, wtih cutting and grounding of the MT line; - The three EEI model 250 inverters; - The MT / LT 20 / 0.4 kV transformer, which is rated 1000 kVA; - The auxiliary frame (conditioning, lighting and service outlets, etc.). - An uninterruptible power supply (UPS) to supply ancillary services and protections for electrical substations. - The GSE measurement groups for the energy produced and promoted installed on the AC side at low voltage at the parallel point of the inverters; The connection between the Enel delivery area and the MT frame will be implemented with three wire unipolar cable of type RG7H1R 12/20 kV, section 95 mm 2. The general device (GD) will consist of an automatic MT switch, equipped with a circuit for opening and a coil for absence of tension on which the general protection (GP) will act, the switch will be of fixed type, combined with a three-pole switch on the network side. The switch will be equipped with a protection system consisting of:
