INTRODUCTION

The existing 30 years old infrastructure was ageing and needed an upgradation to carry an increased load and to improve quality of power. The line had to be converted from 66 kV S/C to 110kV D/C to further improve stability.

KSEB was struggling with the thirty-year old network around which towns grew, leaving no chance for construction of any new line. As the town grew, so did the power needs. This old line was built to cater to the needs of the population on a S/C 66KV line. Solution was required to facilitate the increase in load and improve quality of power. To achieve this, KSEB decided to voltage upgrade the line while providing double circuit line for reliability. Challenge was the space available due to dense vegetation and uneven topography.
