Flicker Analysis
Flicker is a name given to frequent voltage variations caused by cyclical loads. The most troublesome aspect of flicker is usually the visible variations in output of incandescent lamps and TV screens in plants and neighboring homes.
Quality-control problems or production interruptions can also be the result of severe flicker. Flicker can be caused by arc furnaces, welders, thyristor-fed DC drives, reciprocating compressors, chipper drives, hammer mills and frequent motor starting. Available solutions to a flicker problem include alterations to operator control, var compensation, or system configurations.
ESA expert engineers conduct measurements and analysis to determine cost-effective solutions to control flicker issues.
