HPPT Pumping Plant

Hydro One’s Riverdale High Pressure Pipe Type Pumping Plant, in Ottawa, Canada, was originally installed as an oil pressurization facility for a single circuit then expanded to service an additional circuit that required a second oil reservoir to be installed alongside but remote from the original plant. The control systems were also modified to a unique design which has become obsolete with no spare parts, thus, the pumping plants had reached end of life and requires replacement. EHV supplied, installed and tested of PLC controlled 2-circuit pressurization plant servicing 115kV underground cable circuits.
