Oxford Falls Telecommunications Facility – UPS LCR

“Satellite Station has it’s outdated No-Break Power System (NBPS) upgraded”

The condition of this sites existing Thycon 6 x 150 kVA NBPS (arranged in a synchronized parallel redundant ‘N+1’ configuration) had deteriorated and the system was unreliable. Space limitations within the exchange required the equipment to be cut over in stages, the first of which involving decommissioning two redundant UPS’s, creating space to install and commission the first 300KVA new APC Schneider UPS. After site commissioning and load testing the new UPS supported full building load whilst the remainder of the system was decommissioned and removed. In the final stage, a second new UPS was installed and commissioned on a full redundant ‘2N’ arrangement c/w with new Input / Output Switchboards.


Despite the barriers associated with limited space and out-dated unreliable systems, all stages of integrity testing, replacement and migration were successful due to strategic minute-to-minute program planning, structured contingency management and strong team communication. Ongoing communication with the major regional and international stakeholders ensured all expectations were met and there was no disruption to this strategic Telepower facility.

The old NBPS system and associated input and output paralleling switchboards were replaced with a new UPS system comprising of:

  • 2 x new APC 300kVA UPS System.
  • 2 x new 800Amp ATS UPS Input Distribution Boards
  • 2 x new 800Amp UPS Output Distribution Boards
  • 3 x 300Amp MIMs to Cable Junction Boxes
  • 240mm² Fire Rated Cable Submains installed to AS3013
  • Decommissioning and removal of redundant static switches within existing UPS DB’s
  • AMS installation to all new electrical equipment.
  • Demolition and removal of existing 6 x 1.5 tonne UPS System and associated batteries.
  • Material handling and storage with limited space and disruption to the building operations.
  • On site Dummy Load Testing of new APC UPS
  • Air Conditioning Duct Work Modifications
