Many utility customers suffer from unplanned production stoppages and frequently they believe that these events are due to loss of power, or service interruption from the utility. Sometimes they are correct but most of such unplanned events are due to voltage sags. In order to provide the correct solution to these stoppages, it is important to diagnose the real causes and the primary tool to do this is the installation of a power quality analyzers. These devices measure and record events such as voltage sags and swells, detect and measure harmonic voltages and currents, flicker and energy parameters.
"The results were dramatic. Productivity losses from sags with the protected saws were reduced to zero. I can say with absolute confidence the payback was well under a year. Now my only problem is that production managers want to know why we didn’t protect the rest of the wire saws with the AVC. Every time a thunderstorm appears in our area, we have to shut down the unprotected saws until the storm passes.”
