Voltage dips, short interruptions, immunity tests (IEC 61000-4-11)
Electrical and electronic equipment can be affected by voltage dips and short interruptions of the power supply. They occur due to faults in a (public or non-public) network or in installations by sudden changes of large loads. In certain cases, two or more consecutive dips or interruptions can occur.
The IEC/EN 61000-4-11 standard is about immunity testing (measurement techniques) of voltage dips, short interruptions and voltage variations. IEC 61000-4-11 defines the immunity test methods and test levels for electrical and electronic equipment connected to low-voltage power supply networks for:
