IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Hydraulic analysis of oil spill control systems at electrical transformer stations
Author : JAMES LI(1) & CELIA FAN(2)
(mixture of paraffins, naphthenes and aromatic compounds) is used to increase the efficiency of the electrical voltage
transfer and reduce the moisture and air at electrical transformers. Each year, there is a high probability of spilling transformer oil
accidentally from electrical transformer stations to the water environment in Ontario, Canada. In order to control these spills, oil spill
control system are installed at electrical transformer stations. These on-site oil spill control systems, either electrically- or hydraulicallybased,
use the concept of different specific gravities between oil and water for oil separation and containment. It is also assumed that
the trapped transformer oil in the oil spill control system will be held for a short period of time and subsequent cleanup mechanism will
remove the spilled oil. At a non-staffed transformer station in Ontario, Canada, a sudden surge of oil spills may be trapped by its
hydraulically-based oil spill control system. However, the trapped transformer oil may not be cleaned up right away and may be
flushed out during subsequent severe rain storms. The objective of the research project was to investigate the oil trapping
performance of the proposed oil spill control system at a Hydro One’s transformer station near the City of Burlington, Ontario, Canada.
It focused on the analysis of oil trapping performance of this system during a major spill event as well as the potential flushing of
trapped oil from the spill control system under severe storm events. Using a scaled physical model (1:12) and the actual transformer
oil used at the station, the performance of this oil/water separator system was analyzed. The study results indicate that (1) major
transformer oil spills can be trapped by the proposed API oil control system under dry and wet weather flow conditions; and (2) the
flushing of the trapped oil out of the proposed system is low even by rainfall events more severe than the 100 year design storm.Form Required :
