A distribution system connects consumers to the high voltage transmission system. Due to the lower voltage, and therefore higher current, the I2R loss in a distribution system is significantly higher than that in a high-voltage transmission system. Resistance is more dominant in the distribution system and is also sensitive to temperature.1.2 Classification of Distribution Systems: A distribution system can be classified based on:1.2.1 Nature of Current: Based on the nature of the current, the system distribution system can be relegated as (a) DC distribution system and (b) AC distribution system. Nowadays AC system is universally adopted for electricity distribution as it is simpler and cheaper than DC distribution system.1.2.2 Types of Construction: Based on the type of construction the distribution system can be relegated such as (a) on overhead system and (b) underground system (via cables). The operation and maintenance of the overhead system is 5 to 10 times cheaper than the equivalent capacity of the underground system, in general, the underground system is used in places where the overhead system is infeasible or prohibited by local laws.1.2.3 Scheme Of
