Study on the ageing of insulators based on the surface charge accumulation process
The Journal of Engineering, 2019 In order to study the transient motion of the space charge around the air tower insulator and the charge distribution of the insulator, a two-dimensional mixed numerical model of the insulator string based on chemical reaction is proposed. The simulation

Streamers in air splitting into three branches [PDF]
, 2013 We investigate the branching of positive streamers in air and present the first systematic investigation of splitting into more than two branches. We study discharges in 100 mbar artificial air that is exposed to voltage pulses of 10 kV applied to a ...

Surface Damage under Tribological Conditions Induced by Electrical Discharge
Tribology Online, 2019 We have seen small black spots or craters on the surface of worn machine parts. They are considered to be caused by discharges of static electricity. However, there is no clear evidence of being caused by discharges of static electricity, as nobody can ...
