SagFighter Outperforms – Here’s the Data That Proves It
A voltage sag is the drop below 90% of the RMS voltage on a power system for a duration of time ranging from a cycle of the AC voltage to a minute. They are far more common than interruptions, and can damage many types of industrial equipment and processes. A voltage sag lasting only 100 milliseconds can cause a shut-down of equipment in a manufacturing process leading to hours of down time and lost revenue.
This paper presents an analytical description of different types of sags, with the actual and calculated performance data for UST’s SagFighter.™
