In transmission line system the parallel power lines are placed to deliver the power from the feeders to the load side areas. In this situation the unbalanced voltage and current conditions will affects the consumers loads, especially the AC power sources will produce enormous issues in the power quality system. To avoid this problems the automated monitoring and controlling of the transmission line system is introduced. This monitoring and controlling of parallel lines done by number of methods like wired, wireless, electrical, and electronics based and so on. The advancement of the embedded system will leads the parallel line protection with effective way. One of the major systems for the TX line is WSN based monitoring and controlling in this concept the WSN is interfaced with the contact less sensors. © 2020 Elsevier B.V., All rights reserved.
