A 480V, 3 phase supply delivers power to a wye connected load with impedance of 10+j5 ohms per phase and a wye connected purely resistive load with impedance of 15+j0 ohms per phase. What is the average power of one phase in KW?
INSTRUCTIONS:
I really need to understand this. Please follow and I'll give an upvote without any questions. Do not answer if you don't know, please I'm trying to study while working.
• If using calculator, please input at the solution. Example: "Just click at 'Mode 2 5" like that
• Always write the complete formula including derivation of the fomula
• When writing a formula, please input the exact word terminology. Example: Ia = Van/Zan where Ia is a phase A line current
• Always put explanation at the computation.
