Scope (English)

This standard is intended to provide the characteristics required for the safety of electrical installations in the event of voltage disturbance and electromagnetic interference from different causes. By defining the general chapter, scope, reference document, protection of low-voltage electrical installations from transient overvoltages from ground faults in high-voltage systems and from faults in low-voltage systems, protection against transient overpressure from the atmosphere or from switching, electromagnetic influence protection measures, and under-voltage protection.
