Chapter 8, Problem 8.12P

A Y-connected load bank with a three-phase rating of 500 kVA and 2300 V consists of three identical resistors of 10.58 Ω . The load bank has the following applied voltages: V a b = 1840 82.8 ° , V b c = 2760 41.4 ° , and V c a = 2300 180 ° V . Determine the symmetrical components of (a) the line-to-line voltages V a b 0 , V a b 1 , and V a b 2 , (b) the line-to-neutral voltages and V a n 0 , V a n 1 , and V a n 2 , (c) and the line currents I a 0 , I a 1 , and I a 2 . (Note that the absence of a neutral connection means that zero-sequence currents are not present.)
