Application Summary AI generated
This standard specifies the immunity test method for electrical and electronic equipment against unbalanced three-phase supply voltages. It is applied in EMC testing to verify that equipment, such as industrial drives, power supplies, and grid-connected devices, can operate reliably under voltage unbalance conditions. The standard is relevant for manufacturers and testing laboratories assessing product robustness in power distribution networks.
