Explain how the performance of induction motor can be predicted by circle diagram. Draw the circle
diagram for a 3-phase, mesh-connected, 22.38 kW, 500-V, 4-pole, 50-Hz induction motor. The data
below give the measurements of line current, voltage and reading of two wattmeters connected to
measure the input :
No load 500 V 8.3 A 2.85 kW − 1.35 kW
Short circuit 100 V 32 A − 0.75 kW 2.35 kW
