Abstract Adjustable speed drivers (ASDs) are sensitive to voltage sags, and the tolerance to voltage sag is easily affected by different factors. In this paper, with the dynamic equations of DC circuit and asynchronous motor, mechanism analysis of ASDs’ factors (protection, control methods), load factors (load characteristics) and voltage sag characteristics (voltage sag types, pre/post-voltage sag magnitude, the shape of voltage sag) on ASD was carried out. On the basis of the analysis and existing standard, a voltage sag tolerance test method of ASD for full parameters was proposed. In view of the characteristics of the ASD tolerance curve, a selection method of test points that can improve the test efficiency to a certain extent was proposed, i.e. Improved Box-in method. It can provide a basis for quantifying the tolerance ability of ASDs to voltage sags and provide reference for standard setting, equipment manufacturing and power quality control.
