Supply of continuous power will be the most important aspect of a transmission line network during emergency time. Many Transmission Lines in India are constructed long time back. So, they are having old aging transmission system life and aging equipment which leads to higher probabilities of failure, higher maintenance cost and higher replacement cost. So, aging equipment needs to be replaced and this replacement should be planned in coordination with capacity additions in any. As the demand for power is increased and various technological development has been tested and approved for better equipments to be selected with reference to the geographical location and weather condition of the line routes. Nowadays, many high voltage transmission lines have been developed worldwide and are successfully being operated in developed nations. In Indian transmission scenario are progressing towards establishing 765 KV lines to strengthen in recent trends its transmission infrastructure. Massive expansion of the inter-state transmission system is under way to provide to the transmission requirement of new generation projects. Transmission line failures occur due to harsh weather and non-climatic reasons such as human errors and mechanical failures. While it is impossible to prevent all such situations, electrical utility officials and contractors must be equipped to meet such emergencies. Emergency Restoration System Towers were a temporary solution designed to bypass the existing transmission towers of any voltage in any terrain. They will be used until the main line is re-conductored or restored. Planning includes determining which transmission lines are important and the possible ways in which they can fail and how best to restore them. This includes general information about existing structures and foundations, data on past weather related failures, weather criteria and structural loading and the extent of damages. To compound this difficult situation, large amounts of inventory were required in order to have spare lattice towers available for emergency restoration work. In India, Power Grid Corporation of India inherited more than 100 different types of designs of transmission suspension towers and transmission tension or dead-end towers. In this paper, it has been analysed for various reasons for frequent failure of transmission lines in various parts of India. Also, analysed various necessity for the transmission line utilities to take precautionary actions to avoid and reduce these disruptions. Then discussed about various recent innovation technologies and transmission components which can be used for the better operation and maintenance of the transmission lines in Indian conditions and standards adopted.
