Özet:

 

The insulating outer-sheath of ADSS (All dielectric self  supporting) cables used on high voltage transmission lines are often  subjected to various environmental effects.  The ageing process of  cable sheath can be investigated by using the dry-band arcing test  method under laboratory conditions.  Dry-band arcing is the most  common technique to determine the ageing period of insulating  materials.  Environmental effects such as rain, humidity, dew and ice  produce various amounts of wet regions on the cable surface.  Electrical arcs and hence degradations are occurred on the cable  surface due to the enhanced electrical field with formation of wet  regions.  In this study, the ageing process of ADSS cables was  investigated by using the dry band arcing test method (IEEE 1222  Electrical surface degradation).  Rainfall intensity determines the  wet regions on the cable surface which affects the ageing process of  the cable.  During tests electrical arc signals were investigated by  analyzing wet region scope versus amplitude and frequency spectrum  variations via the FFT method.  It is possible to claim that the  proposed FFT analysis clearly identifies the ageing period of the ADSS  cable which was subjected to different rainfall intensities by  monitoring frequency spectrum of the arc signals.
