The committee was formed by the Government of India in the year 1949.The objective of the PTCC is to ensure the safety of telecommunication equipment and precious human lives of personnel working in the concerned organizations as also those working in the close vicinity of power transmission line. The role of the committee is to deal with route approval for all new power lines . The PTCC have issued guidelines and manuals from time to time for preparation of proposals for clearance. The norms are reviewed by PTCC to affect changes in line with the technological advancements and bringing safety standards. The clearance of this committee is required before energization of new power lines of 11KV and above, which is given after obtaining clearances from the Railway/Telecom having lines in the area. 2.2 Various committees connected with Power and Telecommunication Co- ordination: i. Central Standing Committee: This consists of two representatives from DOT and two from Central Electricity Authority (CEA).This was set up by the high level committee to look into estimates, which have resulted in delay in settling re-engineering cases. ii. High Level Committee: This is a committee at the level of secretaries or Chairman/Members of the Board from Power and Telecommunication sectors. The committee is assisted by officers from the two sides. Cases where no consensus could be arrived at the level of the central PTCC are referred to this committee.
