Unformatted text preview: b) Repeat for the case where the load power factor is 0.707 lagging (Answer: 131V). c) Repeat for the case where the load power factor is 0 leading (Answer: 113V). Special problem #2 Three singlephase loads are connected in parallel across a 60Hz source of 240 Volts. Load #1: 6 KVA at 0.8 power factor lag Load #2: 4 KW at 0.9 power factor lag Load #3: 13 Amps at unity power factor a) Find the total complex power consumed by these three loads. b) Find the source current magnitude (Answer: 54.76 Amps) c) Find the value of capacitive VARS that should be added in parallel to these three loads to make the overall power factor 0.95 lag. (Answer: 1,619 Vars)...
