Power Quality: Top Protection

The Power Quality problems of an electrical distribution network are often generated locally within the structures and can depend on various situations, such as, for example, construction works, switching on high loads, faulty distribution components and particular basic electrical disturbances.

Furthermore, external causes such as atmospheric events (hurricanes, lightning, snow, ice and floods), equipment failures, short circuits, and load switching operations can generate additional power quality problems especially on very large power distribution lines.

Particularly complex power quality problems can be characterized by the combination of several unwanted electrical perturbations such as voltage surges, high frequency conducted disturbances and voltage spikes.
