Challenges in Preparation of Detailed Project Report for High Voltage Distribution System (HVDS) Scheme – A Case Study

High Voltage Distribution System (HVDS) is being implemented in many utilities across our Nation. In rural areas, loads particularly agricultural consumers are widely dispersed and low tension lines of 433 V run for long distances to feed a small load. Two or three low tension spans are to be laid to fetch a load of one pump set and such 30 to 40 pump sets are connected on each distribution transformer of 63 kVA or 100 kVA. These transformers are generally overloaded due to long LT lines and more number of consumers connected. This paper describes about the various aspects in preparing HVDS scheme on an overloaded 100 kVA transformer and its Cost Benefit Analysis (CBA).
