New ABP 11kV Supply (No.7) – Retain ABP Supply to No.3 (3.3kV)
An option is to obtain a new 11kV supply to the terminal. This would be sited adjacent to
No.7 Switchroom and supply the LV board within. LV supplies would be distributed from
this point to No.3 and No.6 switchrooms, replacing LV supplies at those locations.
If this option became available the order of proposed works is as follows.
1.
Provide new 11000/400V transformer at No.7 Switchroom. LV board is capable of
accepting up to 2MVA transformer.
2.
Build a new LV switchroom adjacent to existing No.3 switchroom and supply this
from No.7 Switchroom LV Board
3.
Transfer loads from existing No.3 switchroom to new switchroom. On completion
the existing No.3 switchroom becomes a dedicated 3.3kV switchroom.
A single line diagram is shown below for this solution.
