What is it about?
Modelling explained that the β-factor from a micro-tip on a high-voltage line can be decreased with dependence from contact angles. It has been shown that highly porous and hygroscopic properties of the modified surface reduce the contact angle of water droplets on the wire and the β-factor from the rough surface due to the dielectric shielding. Newly engineered surfaces allow for control of the contact angle of a water droplet on the wire and also reduce the β-factor, in comparison with an uncoated surface.

Why is it important?
A crucial amount of the power grid is based on the overhead high voltage alternating current (HVAC) transmission lines, due to their large transmission capacity and economic feasibility. Thus, a new approach is urgently needed to reduce the corona losses.
