The Dynamic Sag Corrector (DySC) for Mitigation of Voltage Sag in Power System

The Voltage sags are always seen as a huge threat to the various devices in electric power system as well as to the domestic and commercial equipments. Voltage sags affects the productivity of the industrial sectors causing them a huge loss. There were many solutions and electronic equipments have been proposed to mitigate such kind of voltage sags. The series parallel connected Dynamic Sag Correctors (DySC) is evaluated which provides significant protection against the sag problems at greatly reduced cost. The Dynamic Sag Corrector (DySC) features that its size and weight is reduced as compared to the other protective equipments. DySC is basically rated from 1.5 KVA one phase to 2000 KVA three phase. This paper presents detailed discussion of DySC configurations and its operating principles and it is compared with other sag mitigating devices. It also provides the basic conditions under which this new category of product can be applied.
