How to Solve: Line to Ground Faults with Symmetrical Components - (Electrical Power PE Exam)
A single line to ground fault occurs on a three-phase, 230 kV, 500 MVA transmission line. Use symmetrical components to solve for all current and voltage sequence components. If: Z2 = Z1 = 5Zo and Zo = 0.241 pu, determine the following: A) The positive sequence per unit current component (Ia1_pu) (answer = 0.377 pu) B) The positive sequence current component in amps (Ia1) (answer = 473 A) C) The A line fault current (Isc) (answer = 1,420 A) D) The positive sequence voltage component (Va1) (answer = 72.5kV) E) The negative sequence voltage component (Va2) (answer = -60.3kV) F) The zero sequence voltage component (Va0) (answer = -12.1kV) *In the video it is accidentally written as Va3 instead of Va0 G) The A phase voltage during the fault (Va): (answer = 0V) __________________________________ 👉 Visit the full article on Symmetrical Components Single Line to Ground Faults and print/download the contents of this video: http://www.electricalpereview.com/sym... . **** PE EXAM *** 🔥 SUBSCRIBE for more videos on how to pass the NCEES® Electrical Power PE Exam!    / @electricalpereview  . 🚀 Ready to PASS the NCEES® Electrical Power PE Exam?
