Evaluation of damages due to voltage dips on devices and industrial plants

Evaluation of disrupted operations due to voltage dips on industriai processes depends on thè interaction between equipment sensitivities and characteristics of expected voltage dips on thè electrical network. In case of continuous processes, a multi-motor System driven by a series of adjustable speed drives is required in order to regulate and to maintain Constant thè characteristics of thè end product. In thè paper an alternative electrical scheme for reducing high sensitivities of ASD to voltage dips is proposed and compared with a traditional approach. Finally, costs and benefits of thè proposed solution is discussed for thè case of a paper industry, taken as typical example of multi-motor continuous process
