The highest transmission voltage in India is 765 kV. India’s transmission voltage (highest) is 765 kV AC, and Power Grid Corporation constructs these lines for interstate connectivity across the country. In India, the maximum DC transmission voltage is 800kV. Due to conversion (AC/DC) and inversion (DC/AC) for bulk power transmission, this has limitations.

In India, 765 kV is the maximum transmission voltage. Power Grid Corporation builds these lines for interstate communication throughout the entire nation. India’s transmission voltage (highest) is 765 kV AC. The highest DC transmission voltage in India is 800kV. This is constrained by AC/DC conversion and DC/AC inversion for the transmission of bulk power.
