“…AC breakdown strength of paper is an intrinsic property of dielectric material, independent of the electrode configuration where the electric stress is applied (Amin et al, 2018;Ramli et al, 2014;Zhou & Chen, 2017). The minimum voltage at which the dielectric material fails is known as AC breakdown voltage (Baur et al, 2017;Elanseralathan et al, 2000).…”

This work examines the physical and electrical breakdown characteristics of kenaf paper coated with Polyvinyl Alcohol (PVA) for application in power transformers. The paper was made from kenaf bast fibers using the soda pulping method, whereby the pulps were subjected to 12,000 beating revolutions. PVA with weight percentage concentration up to 6% was introduced to the beaten kenaf through a spin coating approach. The structure of the kenaf paper was examined through Scanning Electron Microscopy (SEM). The physical properties examined were apparent density, Tensile Index (TI), Burst Index (BI), and Tear Index (TeI), while AC breakdown voltage and strength were analyzed for the electrical property. It is found that the beating and external PVA improve the kenaf paper’s apparent density, TI, BI, and AC breakdown strength while the TeI decreases.

“…The methods have been used for years for determining the breakdown voltage of gaseous [24][25][26][27] and liquid insulation [28][29][30][31], and are considered consolidated techniques without questions as to their reliability. However, there are very few studies that analyse the methods themselves [32][33][34], and even in these works their reliability was not analysed as a function of their parameters.…”
