State transco Madhya Pradesh Power Transmission Company Ltd (MPPTCL) recently conducted live-line maintenance on a crucial 400kV line, obviating a potential long-duration outage.
In a release, MPPTCL said that it recently carried out live-line maintenance on the crucial 400kV Indore-Nagada transmission line.
The work was successfully completed on the energized line carrying around 200 MW of power flow, the release said. With this, MPPTCL ensured grid stability and averted a potential long-duration outage of this 400kV line.
The maintenance was carried out for replacing of a disc insulator string on one phase of the 400kV line. Considering the importance of maintaining grid stability during the “Mahashivratri” festival, it was decided to execute the work in live conditions itself, the release noted.
The task was successfully accomplished using a vehicle-mounted insulated aerial work platform along with advanced hot-stick tools and the bare-hand technique. The entire operation was completed without any disruption to power supply.
By undertaking live line maintenance, grid reliability and stability were maintained. The approach helped avoid a potential long shutdown, safeguarded the power exchange option between the Indore and Nagda regions, and prevented possible commercial losses related to transmission charges.
The maintenance work was carried out near Rau, Indore, and was completed by bare-hand trained line maintenance staff from Bhopal, Itarsi, and Indore. The staff worked in coordination, strictly adhering to safety standards and completing the task with utmost caution and efficiency, the release added.
