AC Surge Concept

AC Surge refers to a sudden spike in the electrical current within an AC power supply.
It occurs when a large current is suddenly transmitted through live devices.
These surges typically happen instantaneously and can cause significant damage to electronic equipment if not properly managed.

Causes

Lightning: Lightning strikes can induce powerful voltage surges in the electrical grid.
Power Grid Issues: Fluctuations or faults within the power grid can cause sudden voltage spikes.
High-Power Equipment Switching: The turning on or off of large electrical devices can create surges in the system.
Power Infrastructure Failures: Faults in electrical engineering systems or power lines can lead to voltage surges.

AC Surge Standards

IEEE 587: A standard that defines guidelines for surge protection devices, focusing on the protection of electrical systems against transient voltage spikes.
UL 1449: A safety standard for surge protective devices (SPDs), ensuring that these devices are safe to use and effective in protecting electronic equipment from electrical surges.
IEC 60884: An international standard that specifies the safety requirements for plugs, socket-outlets, and other electrical accessories used in homes and workplaces, including surge protection components.
