Abstract :
The breakdown performance of an advanced synthetic dielectric coolant, poly-α olefin, is compared to conventional transformer oil over a range of temperatures from 10 to 50 °C. The poly-α olefin oil is first benchmarked against conventional transformer oil, and then compared to poly-α olefin oil that has been exposed to a large number of high-energy discharges in order to establish the effects of oil age on performance. The results obtained from the standard ANSI D877 testing procedure are then compared to the results of a modified test procedure
