Location & Affected Areas: • Site: Global Switch - London East – PowerStation ‘B’
This is a scheduled critical maintenance activity involving PowerStation ‘B’ Output Panel B/D2 Bus Coupler B/DR/5 to B/DR/6 & BA/IT/Board LHS. The activity includes: • Pre- and post-maintenance functional checks • Protection testing • Busbar inspections • Isolation of HV Bus Couplers B/DR/5 to B/DR/6 • System validation and reinstatement procedures
This is a standard 5-year intrusive maintenance procedure conducted by Cophill Power Engineering (Q24-0362) and CBRE onsite maintenance teams.
• Medium Risk Level: The maintenance will result in a temporary reduction in resilience but will maintain an N+2 backup system throughout. • The system operates on a Closed Ring topology, and during maintenance, an Open Ring configuration will be in place to ensure continuous service. • Only one side of the system will be worked on at any given time, ensuring minimal disruption. • In the event of a fault, some floors may experience a loss of ‘A’ supply, but DRUPS backup remains in place. • No expected impact on ‘B’ supply areas.
