1. The load at a certain factory consists of the following: (i) 10 kW, pf = 0.6 lagging (ii) 15 kW, rf = 0.5 lagging (iii) 25 kVA, pf = 0.75 lagging (iv) 15 KVAR, pf = 0.8 lagging (v) 22 kw (vi) 5 KVAR, pure inductance (a) Determine the total true power, total reactive power, and total apparent power and power factor. (b) The power factor is to be corrected to 0.95 lagging. Determine the KVAR rating of pure capacitors needed to accomplish this. (c) If a synchronous motor is to be used instead, determine the real power rating of this motor if its power factor is 0.6 leading. (d) If resistive heating units were used instead, determine the real power rating of these devices. %3D %3D %3D
