Hence, cooling has to be improved or heat generation must be reduced to avoid damage of the insulation. In this paper a new method was examined by investigating electrically insulating phase change materials which are able to store latent heat during a phase change from the solid to liquid state in times of high energy demand. To verify the electrically insulating properties of paraffins, one class of phase change materials, a special test cell was designed allowing the determination of breakdown voltage of phase change materials. The measurements on one paraffin sample proved the promising electrical insulating properties and it was shown that the breakdown voltage in the liquid state is comparable … Y1 - 2016 UR - https://ieeexplore.ieee.org/iel7/7541933/7548553/07548675.pdf SN - 978-1-4673-8706-4 SP - 605 EP - 608 PB - IEEE ER - TY - CHAP A1 - Hartmann, Jürgen A1 - Harrer, S.
