AC Surge Concept

Definition: AC Surge refers to a sudden spike in the electrical current within an AC power supply.
Effect on Devices: Live devices experience sudden transmission of large currents during the occurrence of this event.
Potential Damage: The rapid surges that occur instantly would produce disastrous effects on electronic equipment unless proper precautions exist.

Causes

Lightning Strikes: The electrical grid receives powerful voltage surges when lightning causes electrical strikes.
Power Grid Fluctuations: Power grid fluctuations together with power grid faults lead to quick voltage spikes that may harm electrical equipment.
Switching High-Power Equipment: The process of switching high-power equipment results in electrical system surges when users activate or deactivate large electrical devices.
Electrical System Malfunctions: Electrical engineering system malfunctions and broken power line infrastructure both produce voltage surges.

AC Surge Standards

IEEE 587: The IEEE 587 sets rules for surge protection devices that aim to shield electrical systems from brief high voltages known as transient voltage spikes.
UL 1449 Compliance: Surge protective devices (SPDs) must meet the safety requirements of UL 1449 to prove their effectiveness and security for electronic equipment protection against electrical surges.
IEC 60884: The safety requirements for plugs and socket-outlets together with additional electrical accessories serving both residents and workplaces are defined by IEC 60884 as an international standard.
