A 600V, 60Hz, ∆-connected, 8-pole synchronous motor has a synchronous reactance of 0.15Ω and armature resistance of 0.02Ω. This motor has an output power rating of 46 hp with a 0.90 lagging power factor. Motor losses can be approximated at 1kW.
I don't want a solution.
I only have a question about the lagging power factor of 0.9, is it the angle of the phase current or the angle of the line current?
knowing that delta connected loads phase current relation to line current is:
A 0.9 lagging power factor is :
