ABSTRACT
Voltage flicker is a problem that has existed in the power industry for many years. Many types of end-use
equipment can create voltage flicker, and many types of solution methods are available. Fortunately, the
problem is not overly complex, and it can often be analyzed using fairly simple methods. In many cases,
however, solutions can be expensive. Perhaps the most difficult aspect of the voltage flicker problem has
been the development of a widely accepted definition of just what ‘‘flicker’’ is and how it can be
quantified in terms of measurable quantities.
