संकल्पना:
संतुलित भार की विशेषताएँ निम्नलिखित हैं।
- सभी तीन फेज में परिमाण और फ़ेज़ कोण में समान प्रतिबाधा है।
- सभी फेज में समान शक्ति कारक होता है।
- तटस्थ In के माध्यम से धारा शून्य है।
अनुप्रयोग:
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
तटस्थ तार में धारा 0 A होगी।
