The operator of the distribution system in Croatia, HEP DSO, is installing bird flight diverters on the 35 kV powerline Bilje - Kneževi Vinogradi. The diverters are installed using a drone that can install two diverters with one charge.

They are placed in such a way that the drone is positioned above the protective rope and the diverter clip is lowered under the rope and by a sudden lift, it hooks the clip to the rope, which is then closed. With this activity, more than 13 km of powerlines will be safer for birds and the risk of birds colliding with powerlines will be reduced.
