Zero shutdown Uprating of the transmission Lines: A New technology in Indian Context Shachidevi T.K., Sud Rajat, Yadav Madan G. Sterlite Power Transmission Limited, India Online published on 3 September, 2019. Abstract In India, power demand is increasing in every region and at the same time we have many congested power transmission lines which may need to be augmented by new lines or by uprating the exiting lines. Majority of the times, uprating using high temperature low sag (HTLS) conductor is preferred to increase the amperage using same towers due to non-availability of the right-of-way in many cities. During such change over of the conductor, the line must be shutdown and hence causing power interruptions. This paper is about the possibility of uprating the transmission lines using live line techniques to avoid shutdown during the stringing and change over period and hence improving the reliability and uptime of the line. Top Keywords Live line, Zero shutdown, current uprate, voltage upgrade. Top |
