A 400-kV transmission line has a hot-weather power rating of1400 MVA. If the transmission line is operating in cold weather, itis rated for 2200 MVA (at 400 kV). The transmission line is undercold weather conditions, and the operating voltage is 390 kV. What is the per-unit value of line-to-line voltage and phase voltage with the operating voltage of 390 kV? What is the per-unit ratedcold-weather power if the hot-weather rating is considered to be 1p.u.?
