Furans are a family of organic compounds which are formed by degradation of paper insulation [8]. Overheating, oxidation, acids, and decay caused by high moisture with oxygen accelerate the destruction of insulation and form furanic compounds. As with dissolved gases, increases in furans between DGA tests are important. When furans become greater than 250 parts per billion (ppb), the oil should be reclaimed; paper insulation is being deteriorated and transformer life reduced at a high rate. Look at the IFT and acid number in conjunction with furans. Furanic ******* in the oil is especially helpful in estimating remaining life in the paper insulation, particularly if several prior tests can be compared and trends established. 7.
