A review of the techniques used for power quality monitoring is presented in this paper. Major focus of this paper is on power quality monitoring (PQM) and management systems in the area of power industry. Techniques reviewed in this paper also include some power quality meter placement techniques. Efficiency and cost effectiveness of PQM system can be improved by applying the techniques that find the optimum number of monitors to be placed and the best locations where they have to be placed and these techniques are called power quality meter placement techniques. In this review initially methodology of each method is defined and then comparison between them is presented. Power quality monitoring and management strategies that are used internationally in industries are discussed and at the end som
