28-2 POWER QUALITY
CALITATEA ENERGIEI ELECTRICE
Power quality problems can cause processes and equipment to malfunction or shut down. And the consequences can range from excessive energy costs to complete work stoppage. Obviously, power quality is critical. There are many ways in which a power feed can be poor quality, and so no single figure can completely quantify the quality of a power feed. In this paper we are going to present all definitions, classifications and problems related to power quality. Finally, we have done comparison between the practical measurements and standards related to power quality.
