Is Your Productivity Sagging?
A sag is a 10% to 90% drop in the supply voltage. Sags are short duration events caused by faults on the utility system or by the starting of large motors, and can be accompanied by voltage distortion, transients and phase shifts. Voltage regulation is another potential problem that occurs when voltage fluctuates over 10% for long periods of time from one minute to many hours.
Why are Sags so Costly?
The effects of a voltage sag on a plant or production facility can be devastating. In the United States alone, voltage sags cost production facilities billions of dollars every year in downtime and lost production. The cost of poor power quality depends on many factors, but it generally costs between $50 to $400 per kVA of total load. For a 10 MVA plant, that translates into a cost of between $500,000 to $4 million annually.
