New Precautionary Studies and Results for Reducing Bird Caused Faults in Over Head Lines

Abstract Studies for the prevention of bird-induced malfunctions have been examined in the literature. In studies in the literature, some precautions have been taken to prevent birds from being placed in undesirable dangerous spots on conductors and poles. It has been observed that some of the measures are efficient and some are inefficient. In this direction, a number of measures have been taken to Turkish Transmission Network.When evaluated in terms of the number of individuals and wing spans in Türkiye, storks and seagulls are expected to cause the most malfunctions in OHLs. However, it has been observed that the habitats of seagulls are generally near the sea. It has been observed that storks use OHLs and poles on their migration routes, nesting and resting. It has been determined to the degree that storks are mostly responsible for bird-related malfunctions. Turkish Electricity Transmission Corporation has taken various measures to reduce bird-related faults in OHLs. Sheet galvanized metal assembly was carried out in May 2019. Sheet plates are mounted horizontally (flat) on the middle phase console of the poles. As a result of the studies, it was observed that although horizontally mounted galvanized sheets did not prevent nesting, the number of openings of bird-borne OHLs decreased by a minimum of 63 percent and a maximum of 100 percent.
