13.8.4 example 3
TRANSCRIPT
Find the following values:(a)Determine the line voltage of the delta connected three-
phase generator: VL (Load)(b)Determine the phase voltage of the load: VP (Load)(c)Determine the phase current drawn by the load: IP (Load)(d)Determine the line current delivered to the load: IL (Gen)(e)Determine the phase current in the generator: IP (Gen)
VL = VP = 210 V
Determine the phase voltage of the delta connected three-phase generator: VP (Load)
VLVP = √3 210 VP = 1.732 VP = 121.3V
Determine the phase current drawn by the load: IP (Load)
VPIP = ZP 121.3IP = 20IP = 6.07A
Determine the line current delivered to the load: IL (Gen)
IL = IP = 6.07A
Determine the phase current in the generator: IP (Gen)
IL IP = √3 6.07IP = 1.732IP = 3.5A
