Scope
This part of GB/T17626 specifies the immunity test methods and preferred test level ranges for electrical and electronic equipment connected to low-voltage power supply networks to voltage dips, short interruptions, and voltage changes This section applies to electrical and electronic equipment with a rated input current of no more than 16A per phase connected to a 50 Hz or 60 Hz AC network This section does not apply to electrical and electronic equipment connected to a 400 Hz AC network. The testing of these networks will be covered in future standards The purpose of this section is to establish a general criterion for evaluating the immunity of electrical and electronic equipment to voltage dips, short interruptions, and voltage changes Note: The voltage fluctuation immunity test can be found in GB/T 17626.14-2005 GB/T
