11 KV Substation.
2. Whereas Fig (ii) shows the schematic connections. The transformer and other equipment are mounted on H-type pole (or 4-pole structure). 3. The 11 kV line is connected to the transformer (11kV / 400 V) through gang isolator and fuses. 4. The lightning arresters are installed on the H.T. side to protect the sub-station from lightning strokes. 5.
