Power losses evaluation in low voltage distribution network: a case study of 250 kVA, 11/0.416 kV substation

Nowadays, the electrical system is more complicated duet to continuous growing. Power losses biggest challenges for distribution network operators. There are several causes technical losses. Losses caused by unbalanced phase current one of main reasons which can be minimized small investment through dedicating a line staff. As result connecting many single loads three four wire power supplies, flowing in each will unequal and accordingly there neutral wire. Unbalancing currents phases lead increase conductor temperature resistance higher contribute Loss reduction enormous utility saving. Besides, it increases capacity save money used later future planted system. This study concentrated on amount copper networks as loading wires network. The efficient economic assuming that right procedure applied balance achieve required calculations require little investment.
