This sudden increase in the number of<br \/>\r\nconcerns over power quality problems is a result of the huge increase<br \/>\r\nin the use of non-linear loads. In this paper, power quality evaluation<br \/>\r\nof some distribution networks at Misurata - Libya has been done<br \/>\r\nusing a power quality and energy analyzer (Fluke 437 Series II). The<br \/>\r\nresults of this evaluation are used to minimize the problems of power<br \/>\r\nquality. The analysis shows the main power quality problems that<br \/>\r\nexist and the level of awareness of power quality issues with the aim<br \/>\r\nof generating a start point which can be used as guidelines for<br \/>\r\nresearchers and end users in the field of power systems.<\/p>\r\n","references":"[1] A.
