General Concept

  • Dual active incoming supplies to site at 10 kV
  • Primary MV switchgear designed to increase the power capacity for next phases of data center
  • Transformer substation with EATON modular cell
  • Air-cooled dry transformers 1600 kVA each
  • Diesel-rotary Uninterruptable Power Supply (DRUPS) system build as distributed redundant power source
  • 4/3N back-up scheme

DRUPS

  • Company uses DRUPS as an uninterrupted and back up power supply
  • DRUPS combine the functionality of a battery-powered or flywheel-powered UPS and diesel generator
  • Company uses Hitec Power Protection 1670 kVA machines, as Hitec provide the best local support services among peers
  • 4/3N back-up scheme
  • Four machines combine «power module» which feeds six data halls
  • Each DRUPS unit with own transformer and switchgear located in separated power rooms
  • 12 hours fuel capacity
