%0 Journal Article %T PHASE FAILURE DETECTOR AND THEIR SIGNIFICANCE IN POWER SYSTEM ENGINEERING %A L.S. Ezema %A B.U. Peter %A O.O. Harris %J Academic Research International %D 2012 %I %X Electrical power system engineering comprises power generation, transmission, distribution, and the utilization of electricity. Modern trends in the development of electric power systems explore means of improving efficiency in these stages mentioned. On the demand side, the protection of consumer equipment and appliances from damage and total destruction due to phase failures is an issue of paramount importance mainly in parts of the world with unsteady supply of electricity. In this work we took a detailed look into what a phase failure is and the possible causes. Then we finally explain the details of a method we have developed that detects cases of phase failure and takes the appropriate measure that will save the consumerloads from damages. %K Power System %K Phase failure %K Detector %K Power outage %K Power protection. %U http://www.savap.org.pk/journals/ARInt./Vol.3(2)/2012(3.2-27).pdf
