Increasing electrical energy consumption and demand have made the world highly reliant on electrical power systems. The results indicated that the new and used oil vapour mixtures were not flammable at 25 ☌ and 1 atm, but would become flammable at 77 and 115 ☌.Įlectrical energy is a necessity for all aspects of civilisation. These values were used to construct a flammability diagram. The lower and upper flammability limits (LFL and UFL) of the mixtures were found to be 0.88 and 5.75 vol.% for the new oil and 0.47 and 3.05 vol.% for the used oil, respectively. Approximately 25% of the compounds comprising the new oil sample were alkanes, whereas more than 33% of the used oil sample components were alkanes. The majority of the components were alkanes, alkenes, or alkynes some ketone, alcohol, aromatic, and anhydride species were also detected. The compositions of new and used mineral oil from an electrical substation in Riyadh were analysed using gas chromatography–mass spectrometry, and C 6 to C 41 hydrocarbons were detected. In this work, the risk of fires and explosions due to vaporisation of the hydrocarbon components of mineral oil, which is used as a transformer cooling fluid in electrical substations, was investigated. Overheating of transformer cooling fluids presents a serious hazard. Transformers reduce the voltage from overhead powerlines to voltages acceptable for city/neighbourhood needs.
