Abstract: At present, a large number of sensitive electrical equipment such as frequency converter are widely used in the industrial
field. The anti sag ability of products produced by different manufacturers is also slightly different. In this paper, the anti
voltage sag ability of frequency converters produced by mainstream manufacturers was tested, and the anti sag ability of different
types of frequency converters was obtained.

Key words: voltage sag; frequency converter; load; sag source
