About the project
Installation of new 13.8 kV metal-clad switchgear in the existing Al-Sharaiah (HRS) substation.
Scope of work
SDEC provided the engineering design for installing new 13.8 kV metal-clad switchgear (BB1A and BB1B) in the existing Al-Sharaiah (HRS) substation in Makkah. As the switchgear was added to an existing substation, the design also covered changes to the auxiliary low-voltage AC/DC system, including breaker sizing and AC/DC single line diagrams, updates to the overall single line diagram, revised cabling in the substation basement and the re-configuration of protection for the new switchgear.
Main scope
- Installation of new 13.8 kV metal-clad switchgear (BB1A and BB1B)
- Modification of the auxiliary low-voltage AC/DC power system, including breaker sizing and AC/DC SLDs
- Modifications to the overall SLD where required
- Modification of cabling arrangements in the existing substation basement
- Re-configuration of protection for the 13.8 kV switchgear
