[DC3] Maintenance of HV Stations DATA 2, A/C/F1 and B/D/F2 + transformer TR F1, scheduled 2 days ago

[DC3] Maintenance of HV Stations DATA 2, A/C/F1 and B/D/F2 + transformer TR F1

The planned preventive maintenance consists of :

-maintenance of HV cells on delivery station “DATA2”and sub-station “B/D/F2”and electrical protection tests.

-Replacement of relay DMCR on transformer TR F1The entire electrical load of DC3 is supplied from “DATA1” delivery station.

The “DATA2” delivery station does not supply any load in normal operation mode. Its switching off for this operation will not have any impact on the datacenter electrical supply. The maintenance of HV sub-station and transformer F1 will be realized while the load is supplied by generators.

Impact : This intervention does not present any particular risk of service interruption and will be processed during working hours
