Perform the following substeps to determine the value of the correction capacitor (C) needed for the following application. A 1 Hp split-phase AC motor draws 20 amps at 120 VAC, and has a power factor of 60%. Determine the correction capacitor value needed to increase the power factor to 90%. A. Calculate the apparent power. P = Einx In P = 120 20 P = P=2400 VA (2.4 kVA) B. Calculate the active power based on the current power factor. P = PAX PF T P = 2.4.60 T P P = T pf PF = P P = A A P = 1.44 kW C. Locate the multiplier from the table to increase the power factor from 60% to 90% and multiply the active power by it to determine the correction capacitor value (C). CPTx multiplier C = 1.44.850 P = T (VA) (kW) C= 1.22 kVAR 2. Determine the correction capacitor value needed for the following application. A 37.3 kW three-phase motor draws 75 amps at 460 VAC. You want to correct the power factor from 70 to 95%. (kVAR) (VA) (kW) Cpf = (KVAR) The apparent power (P) is 34.5 KVA, the active power is 24.15 kW, and the value of the correction capacitor to correct the power factor to 95% is 16.69.
