A 12.47 kV, three-phase distribution feeder is 1.9 miles long and can wheel up to 5.5 MVA. Oriole conductors were hung using an equilateral triangular spacing scheme, with conductor spacing of only 6 inches. 1. Considering the very narrow spacing between conductors, determine whether a short t-line model is sufficient to represent the feeder or if a medium model is required. Do so by comparing the ABCD coefficients for each model, expressed in SI units. Assume a 25 C operating temperature. 2. Using the most appropriate model, calculate the voltage regulation when a rated load with 0.95 lagging power factor is attached. kemsil A/SS 18/1 26/7 18/1 26/7 30/7 18/1 DC Olums/1000ft @20C 0.0644 0.0837 0.051 0.0506 0.0502 0.0432 0.0428 GOHz AC (Ohm/1000ft) Capacitive Inductive Reactance Reactance @250 500 750 MOhms-1000ft) (Ohms/1000ft GMR (Ft) 0.0657 0.0723] 0.0788 0.576 0.0934 0.0197 0.06520.0714 0.0778 0.565 0.0881 0.0217 0.0523 0.0574 0.0625 0.56 0.0877 0.0221 0.0517 0.0568 0.0619 0.549 0.0854 0.0244 0.0513 0.0563 0.0614 0.544 0.0843 0.0255 0.0443 0.0487 0.0528 0.544 0.0856 0.024 0.0438 0.0481 0.0525 0.539 0.0835 0.0265 WAXWING 266.8 wwwwwwwwwwwwwwwwwwwwwwwww PARTRIDGE 266.8 MERLIN 336.4 LINNET 336.
