Abstract
Transformers reduce voltage of the power distribution for use by the ultimate user. These transformers include transformer oil that provides electrical insulation and functions as a coolant. A transformer assembly and/or a transformer pad has a secondary containment sump configured to collect transformer oil that may leak from a transformer. The transformer assemblies or transformer pads may also have a second sump to collect water from the bottom of the secondary containment sump or a petroleum plug to allow water to be released from the secondary containment sump but not oil or other petroleum fluids.
