Technical and Economical Analysis of Medium Voltage Distribution Grid of Erzurum on Overload Condition

The electric grid must be reliable and quality for the effective operation of electrical devices. Overcorrect is an important factor for voltage drops. Voltage drop must be within certain limits in a grid. If some power lines were disabled due to fault or maintenance, loading currents passing through from distribution lines or cables are increases. If this situation takes a long time, the safety of the grid will into danger. Voltage drops and the power loading capacity of lines must calculate for all risks when the grid starts to be established. When any equipment fails, the behavior of the electrical grid must be estimated or determined. Electricity consumption generally increases every year. Grid power losses have become important when the load current increases, it is necessary to know these losses because of its technical and economic effects.
