Voltage disturbances

Voltage disturbances are distortions in the electrical wave. They can adversely affect critical industrial equipment, such as automatic controls and electronic motor drives. They are caused by extreme meteorological conditions (lightning, high winds, etc.) or by particular installations.

Optimal electromagnetic compatibility

To minimize voltage disturbances and prevent negative customer impacts, the Vice-présidence Réseau offers high-performance solutions to improve power quality and achieve optimal electromagnetic compatibility between the power grid and sensitive equipment.
