An Effective Method of Segregation of Losses in Distribution Systems

Senior Lecturer in Electrical Engineering BSc. Eng (Moratuwa), MSc (Moratuwa), PhD(HKUST), AMIE (Sri Lanka) Chief Engineer BSc. Eng(Moratuwa), MSc (Moratuwa), CEng. MIE (Sri Lanka) Power system losses have turned out to be a major challenge for electricity utilities worldwide. Bulk of the losses in power system occurs in electricity distribution. The overall energy loss and the distribution system loss in the Sri Lanka power system were about 10% in 2016. Before formulating strategies for loss reduction, it is essential to segregate and determine the losses at each level. Once losses are segregated, utilities can clearly identify their priorities and launch effective programmes to arrest losses.
