This Part of GB/T 17626 defines the immunity test methods and range of preferred test levels for electrical and electronic equipment connected to low-voltage power supply networks for voltage dips, short interruptions, and voltage variations. This Standard applies to electrical and electronic equipment having a rated input current not exceeding 16 A per phase, for connection to 50 Hz or 60 Hz a.c. networks. It does not apply to electrical and electronic equipment for connection to 400 Hz a.c. networks. Tests for these networks will be covered by future IEC standards. The objective of this Standard is to establish a common reference for evaluating the immunity of electrical and electronic equipment when subjected to voltage dips, short interruptions and voltage variations.The voltage rise time, tr, and voltage fall time, tf, during abrupt changes are indicated in Table 4. ... and durations for voltage dips (ts) (50 Hz/60 Hz) Class 1 Case-by-case according to the equipment requirements Class 2 0 % during 0.5 cycle 0anbsp;...
