About this document
Impact of Tower Footing Resistance on Back Flashover by Suresh Chandra Padhy is a document available to read on EtoBox.
This document analyzes how tower footing resistance can affect backflashover across insulators in a 115kV transmission system in northern Thailand. It describes the transmission line between Lampang and Lamphun substations, which is 73km long with double circuits and overhead ground wires on steel towers. Between 1998-2003 there were 78 flashover events on the insulators, 18 of which were caused by lightning. Around 30% of the towers had footing resistances over 10 ohms. The study simulates the effect of va
