4.23 Figure 4.32 shows the conductor configuration of a completely transposed three-phase overhead transurission line with bundled phase conductors. All conductors have a ra- dius of 0.74 cm with a 30-cm bundle spacing. (a) Determine the inductance per phase in mH//km and in mH//mi. (b) Find the inductive line reactance per phase in Omega//mi at 60 Hz For problem 4.23, ignore the conductor radius and determine the conductor GRM for table for 795,000 mils (Drake) conductor. Use the same geometry shown on figure 4.32. 4.25 For the overhead line of configuration shown in Figure 4.33, operating at 60 Hz , and a conductor temperature of 70^(@)C, determine the resistance per phase, inductive re- actance in ohms/mile/phase and the current carrying capacity of the overhead line. The resistance of each conductor in the four-conductor bundle is 0.12 Omega//mi. FIGUR Line configurat Proble For problem 4.26, ignore the conductor resistance given on the problem and use conductor 2156000 cmils (Bluebird). Use the resistance at 25 degrees C at 60 Hz . Use the same geometry given on figure 4.33. please only 4.23
