ধারণা:
নিম্নলিখিত একটি সুষম লোডের বৈশিষ্ট্য.
- সমস্ত তিন-পর্যায়ের মাত্রা এবং ফেজ কোণে একই প্রতিবন্ধকতা রয়েছে
- সমস্ত পর্যায় একই পাওয়ার ফ্যাক্টর আছে
- নিরপেক্ষ In এর মাধ্যমে তড়িৎপ্রবাহ শূন্য।
আবেদন:
Ia = 20∠0°, Ib = 20∠(-120°), Ic = 20∠(120°)
In = Ia + Ib + Ic
\({I_n} = 20∠ 0^\circ + 20∠( - 120^\circ) + 20∠ 120^\circ\)
= 0 A
নিরপেক্ষ তারে তড়িৎপ্রবাহ হবে 0 A
