Technology revolution in the inspection of power transmission lines - A literature review

There are many issues in power system transmission lines maintenance one such issue is the identification of exact hotspots. These hotspots lead to the deterioration of the power system components. If this deterioration is not addressed then cracks on insulators, spacers dampers braking will arise, which may lead to the damages in the transmission system. This damage may lead to power shutdown in the power grid or causality of humans being and animals. The current scenario of transmission system maintenance demands an urgent requirement in the identification of hotspots on the transmission system so that the impact of the damage may be reduced. In the identification of the deterioration in power transmission system, there are several types of inspection methods are available. This paper gives the bibliography survey on research and development in the field of hotspot identification and deterioration caused by it in the transmission lines. This paper analysis 51 published papers in area of hotspot & Impact of deterioration, published in the past 25 years.
