The connection of the substation is divided as. Incoming or power feeder connection (33kv Incoming Line) Power transformer connection via Lighting Arrestor & Busbar; Voltage transformer connection for control and metering. The single line diagram of an 11 KV substation is shown in the figure below. The single line diagram makes the system easy and it provides the facilitates reading of the electrical supply and connection. Main Components of 11kV Substation The working of the electrical equipment used in the substation is explained below in details. Abstract This paper proposes three approaches to classify substation single-line diagrams so it can be used in a power distribution network expansion. With these approaches the expertise shall substation welcome to guvnl. 400 220 66 kv gis r3 feb13 gujarat urja vikas nigam. single line diagram of ac transmission and distribution system. substation layout scribd. single line diagram of substation single line diagram of. © april 2016 ijirt volume 2 issue 11 issn 2349 6002. single line diagram of 11kv substation circuit globe.
