Thus, the system can address terrorism and/or vandalism of a power transformer in a substation. If some radiator fins are shot or otherwise damaged, causing oil to flow out of the cooling system of the transformer, the system can quickly detect and isolate the leak to prevent further damage to the transformer, while also preventing a larger oil spill.
