MAINTENANCE OF DISTRIBUTIONSYSTEM AND REDUCTION OF

ACCIDENTS THEREOFItem Item details Action taken as on 30/3/09 Remarks with programme for

periodic rectification action

Inspection of HT/LT lines, cutting of tree

branches touching the lines

This is a continuous process. Prunning of tree

braches are taken up in a planned way toensure minimum load shedding.

Replacement of damaged stays Whenever such cases are noticed, it is being

replaced.

Repairing of tilted poles if any On priority it is being done.

Restringing of conductors where there

is inadequate clearance as per I.E. rules

Restringing of conductors are being taken up

to increase the clearance. There are also very

old lines with long span and due sagging the

clearance becomes inadequate. In order to

avoid this we are in process to replace such

conductors with new conductors and to set

clearance we are putting intermitant poles.
