The patented Electrostatic System "Ettore Galliani" is based on the distribution of electrostatic impulses (brief voltage spikes of approximately 80 microseconds in duration, occurring at intervals of 2.8 seconds) through the installation of multiple active plant sectors to protect all architectural and structural elements where pigeons commonly perch.

The individual sectors of the active system are interconnected through tiny interconnection lines and powered by an electrostatic pulse generator connected to the common electrical grid.
