“…A criticism may be leveled against the present work regarding the high conductivities used for testing (especially those of 2000 µS/cmand 5000 µS/cm). The answer to this is that there is intense interest as to what happens in higher water conductivities (in case of heavy pollution) and that such high conductivities (and for that matter much higher, up to 22000 µS/cm) were already investigated in [11].…”

Water droplets on the surface of epoxy resin samples were investigated under the influence of uniform electric fields. Several parameters of water droplets were investigated wrt the flashover voltage of the epoxy resin samples, such as water conductivity, droplet volume, number of droplets as well as the positioning of the droplets regarding the electrodes. The droplet behavior is affected by the above mentioned parameters. Perhaps the most striking conclusion is that the flashover voltage depends more on the positioning of the droplets wrt the electrodes than on the droplet volume and/or number of droplets.

“…Dry zones may ensue, then local arcs and finally a flashover. Such a sequence of events is more or less common in both indoor and outdoor high voltage applications, although there are some differences [8,9]. When a droplet becomes unstable because of a deformation, tiny droplets may be rocketed from it.…”

A new class of insulating materials is the class of polymer nanocomposites. In the past twenty-five years, a lot of attention was paid to the various electrical, thermal and mechanical properties of polymer nanocomposite materials. In the present work, epoxy resin samples without and with nanoparticles (0 wt%, 1 wt%, 3 wt%, 5 wt%, and 10 wt%) are investigated regarding the surface discharges and the flashover voltages. Four different water droplet arrangements were used, with eight different water conductivities in order to see the effect of the nanoparticle.

This paper deals with the flashover voltages on samples of silicone rubber/ethylene propylene diene monomer (SiR/EPDM) mixtures under the influence of a uniform electric field. Five different mixtures of SiR/EPDM were investigated. Various SiR/EPDM mixtures (100% EPDM, 10% SiR + 90% EPDM, 30% SiR + 70% EPDM, 50% SiR + 50% EPDM, 70% SiR + 30% EPDM, 90% SiR + 10% EPDM, 100% SiR) were tested for different water droplet arrangements, different water conductivities, different droplet volumes as well as different droplet positioning w.r.t. the electrodes. The 50% SiR + 50% EPDM mixture proved to be the best mixture regarding the flashover voltage.
