Q. A delta-connected, 3.7 kW, 400 V(line), three-phase, 4-pole, 50-Hz squirrel-cage induction motor has the following equivalent circuit parameters per phase referred to the stator:
𝑅1 = 5.39 Ω, 𝑅2 = 5.72 Ω, 𝑋1 = 𝑋2 = 8.22 Ω. Neglect shunt branch in the equivalent circuit. The starting line current in amperes (round off to two decimal places) when it is
connected to a 100 V (line), 10 Hz, three-phase AC source is .
Solution:
