Unauthorised construction too leads to power cuts
Claiming that unauthorised structures under transmission lines were also causing disruption in power supply in some parts of the capital, transmission company Delhi Transco has written to the land-owning agencies to clear the illegal constructions.
“Delhi Transco has written to the agencies to remove the obstacles in the right of way of the transmission lines, but to no avail,” a Delhi Transco official said.
Besides, notices have also been issued to the owners of the unauthorised structures to remove the encroachments, added the official.
Officials said Delhi has sufficient power but people have to suffer of long power cuts because of the tripping of lines, which occurs because of these unauthorised structures and other encroachments in the vicinity of the transmission lines.
“As per electricity rules the vertical clearance for a 400KV line is 7.3 metre and for a 220KV line it is 5.5 metre. The horizontal clearance for a 400KV line is 5.7 metre and for 220KV line it is 3.8 metre. Besides, a 35 metre right of way is required for a 220KV transmission line (17.5 metre each side) and it is 52 metre for a 400KV line (26 metre each side),” an official said.
Any construction or even planting a tree within this limit is illegal and may cause hindrance in smooth supply of power, added the official.
Transmission company officials claimed that power supply was disrupted in Sangam Vihar and Okhla area of South Delhi on Thursday due to tripping of Mehrauli and Okhla lines.
Officials said when a transmission line trips due to such reasons, it takes a long time to identify the problem spot and remove the obstacles.
“The transmission corridor needs to be kept free from all obstacles for smooth and efficient transmission of power as well as maintenance of transmission lines. It is also essential for safety of the general public,” the official said.
