1. Statement A star connected load of 3300 kVA at 18 kV and a power factor of 0,8 lagging is supplied by a three-phase transmission line having a resistance of 4Ω per phase and an inductive reactance of 7Ω per phase. Determine: a. the sending-end voltage b. the percentage regulation c. the efficiency of the line 2. The attempt at a solution I've attached my attempt at this. i'm confused on what ''sending-end voltage'' is. also do i need to workout the impedance for this.
