The statistical scatter of breakdown voltages of transformer oil - Part III

Sažetak
The third part of the article about coefficients of variation (CV%) of breakdown voltage (BDV) of transformer oil discusses area effect and volume effect. Apparently, BDV decreases linearly with area on a logarithmic scale, but this does not apply to CV%. There is currently little data to make any quantitative recommendations. With an increase in the stressed oil volume by orders of magnitude, CV% decreases several times, but this estimate requires verification.
