The aim of this paper is to evaluate some major criteria for selection and contribution of LV feeder in loss reduction projects. In other word in this paper the relevancy of the measuring of the above parameter to detect the critical feeder for loss reduction project is evaluated. The results of analysis and evaluation of relation between LV feeder’s lengths, load torque and voltage drop with it loss is considered. All LV feeders in Bonab city of East Azarbaijan in Iran is used as study case as a large real LV network. In this case the data of 539 LV feeders are converted and modeled in DIgSILENT software in details and the correlation between parameters is calculated. The results show that there is not strong dependency between LV feeder’s length and feeder load torque with feeder loss, in contrary a strong relation is found between LV feeder’s voltage drop and it loss. Based on the results the most reliable and robust criteria to find the critical feeder for loss reduction is its voltage drop.
