The 500kV High Voltage Direct Current (HVDC) Reduction and Low Side Load Rejection (LSLR) Work at the Riel Station consisted of the construction of ten panels located in four separate buildings. The ten panels are divided into an “A ” (5 Panels) and a “ B “ (5 Panels) redundancy scheme. Tri-Star Automation constructed the panels, placed them onsite and provided the interconnecting field wiring between the panels including, fibre optic cables.
