Note Unless otherwise specified, three phase systems are rated in terms of their line-to-line rms voltages So, for instance, a three-phase 230 kV transmission line has an rms phase voltage of 230/V3 kV. If you encounter a three-phase system specified with two voltages, e.g., 480/277 V, that implies that the line-to-line rms voltage is 480 V and the rms phase voltage is 277 v. Problem 8 The line-to-line voltage of a three-phase transmission line is Vbc-120 2.20° kV. Suppose the...
