Analyzes three-phase AC power systems used in industrial applications. Calculates power, current, and relationships between phases.
ସୂତ୍ର
Line voltage = phase voltage × √3
ଷ୍ଟେପ୍-ଷ୍ଟେପ୍ ଗାଇଡ୍ |
- 1Three sinusoidal voltages 120° apart
- 2Line voltage = phase voltage × √3
- 3Line current = phase current (Y-connection) or √3 × phase current (delta)
- 4Power = √3 × V × I × PF
ସମାଧାନ ହୋଇଥିବା ଉଦାହରଣ
ଇନପୁଟ୍
Line voltage 480V
ଫଳ
Phase 277V

ବାରମ୍ବାର ଜିଜ୍ଞାସା
Why is three-phase used in industry?
More efficient power distribution, smaller cables, smoother motors, better line utilization.
What's Y vs. delta connection?
Y (star): common on supply side, neutral available; delta: high voltage, no neutral.
