Step 5: Calculate the value of a diverter resistance (1.4.2) To achieve level compounding, the series field must provide an MMF of 3600 AT/pole (calculated in Step 4). The actual series field coil has N_se,actual = 18 turns per pole. The current required to flow through the series field winding (I_se) to produce this MMF is: I_se = Required MMFN_se,actual I_se = 3600 AT/pole18 turns/pole I_se = 200 A The total armature current (I_a) is 255.4 A (calculated in Step 4). This current splits between the series field winding and the diverter resistance. The current that must flow through the diverter (I_div) is: I_div = I_a - I_se I_div = 255.4 A - 200 A I_div = 55.4 A The total series field resistance (R_se) is given as 0.2 . The voltage drop across the series field winding (V_se) is: V_se = I_se × R_se V_se = 200 A × 0.2 V_se = 40 V Since the diverter resistance is in parallel with the series field winding, the voltage across the diverter is also 40 V. The value of the diverter resistance (R_div) is: R_div = V_seI_div R_div = 40 V55.4 A R_div ≈ 0.722 The value of the diverter resistance is 0.722 . That's 2 down. 3 left today — send the next one.
