Abstract
Refrigerator and heating cabinet fires due to the dielectric breakdown of electronic components caused by leaked beverages are being reported frequently. On the other hand, there has been little interest in measuring the electrical characteristics of beverages and studying the cause of fires. In this paper, the electrical conductivity and total dissolved solids (TDS) for 32 different beverages commonly sold in South Korea were measured to study the relationship between the electrical conductivity and dielectric breakdown. Out of these 32 beverages, based on the measurements, some characteristic beverages were selected and further dielectric breakdown tests were conducted. The results showed that the probability of a fire is higher for beverages with high electrical conductivity. Interestingly, beverages with low electrical conductivity had a high likelihood of fire depending on the type of beverage. Moreover, some conditions that cause spark ignition, which lead to fires in electronic components, were identified.
