Abstract: Close Proximity Operation of HVAC and HVDC transmission line is the recent trend for increase of power transmission capacity. Need for same is becoming vital day by day due to ever increasing power demand. Erection of HVAC lines has a requirement of high right of way (ROW) as compared to the HVDC lines. Also recent past has witnessed constraint in availability of ROW for many projects of Indian Power Grid. Raise in transmission voltage level of HVDC from Power Grid Corporation of India Limited (PGCIL) and its suitability to decentralized non-conventional grids has led to addition of many upcoming HVDC projects with the already existing ones. So the need of analysis for electric field distribution under this type of hybrid transmission corridor is necessary to meet the standards of engineering design, exposure limits to living beings and environmental protection. The most likely formation of close proximity operations for all the five power grid regions of India has been identified and the electric field distribution has been analyzed with COMSOL Multiphysics. Results so obtained has been discussed with reference to regulation of Indian Electricity Rule 1956 and International Commission on Non-Ionizing Radiation Protection (ICNIRP) guidelines.
