Intervention on 400 kV network. Power cut ~6h
Temperature at the bottom of the DFBAs HCM> 100 K, and DSLC T>100K
ELQA needed on all Sectors (except S. 1-2)
OPTION 3  Potential
Intervention on 400 kV network, with reduced duration of the power cut
Temperature at the bottom of the DFBAs HCM< 100 K, and DSLC T<100K
