Three parallel three-phase loads are supplied from a 480v (line-line rms), 60 hz three-phase supply. the loads are as follows: load 1: a 20hp motor operating at full load, 90% efficiency and a 0.8 lagging power factor. load 2: a balanced resistive load that draws a total of 20kw. load 3: a y-connected capacitor bank with a total rating of 20kvar. what is the total system kw ?
Answers: 1
= 0 due to purely capacitiveload 
= -20 Var
