High Voltage Engineering

The Table 1 below shows results of experiment in determining strength of two (2) different types transformer's oils. Determine the power law for breakdown and hence estimate the breakdown strength for a 0.9 cm gap (kV/cm). Discuss and conclude the experiment results Table 1: Voltage at breakdown for two types of oil with five different electrodes gaps 2 4 6 8 10 Gap Spacing (mm) BD Voltage Oil A (kV) BD Voltage Oil B (kV) 85 130 170 210 245 60 140 220 300 405
