High rate of failures on one HV overhead transmission line caused by birds

Abstract

About a half of birds migrating from Europe to Africa cross over the temtory of Israel and many of them stay in Israel for wintering.The paper presents the analysis of the high number of transient failures recorded on a high voltage 0 overhead transmission line which leads to the conclusion that in the most cases the cause was bird drops(excretions).

“…These acts cause not only transmission line faults, but also huge economic losses. They are the important sources of power system transient fault [1]- [3]. The acts contain such situations: (1) When they are nesting, the materials sometimes drop, causing short circuits.…”
