Voltage sag is one of the most important power quality problems affecting large power customers. It can cause misoperations of customer's sensitive devices and severe economic losses. However, most studies focused on the general principles and characteristics of voltage sag but not specific problems in the given customers. In this paper, two large power customers are taken into consideration. The objective is to try to find out the causes of voltage sags in them. Voltage sags recorded by… CONTINUE READING
