Lloydminster Switching Station was originally a 230kV/138kV switching station with no distribution. This project added a 138kV/25kV transformer and distribution bays. As a result of the prototype deployment of the D400 the SCADA design at Lloydminster is unique. This project added uniqueness giving the substation SCADA, separate from the original D400.

Besides the routine installation and commissioning, the project included a transformer with integrated “Smart devices.” The transformer featured an ABB mini controller, networked to the Beckwith AVR, Weschler temperature monitor, and Calisto oil monitor. Typically, physical conditions are applied to sensors during commissioning and maintenance to trigger protection and control systems. However, applying dissolved gases to transformer oil for the Calisto was impractical. To overcome this, I developed a procedure using a laptop with TeleNet to manually adjust register values and verify that the D400 read them correctly. To share this knowledge I authored a procedure including screenshots which remains in use a decade later.
