संकल्पना:
संतुलित भाराची वैशिष्ट्ये खालीलप्रमाणे आहेत.
- सर्व तीन-टप्प्यांमध्ये परिमाण आणि प्रावस्था कोनामध्ये समान प्रतिबाधा आहे
- सर्व टप्प्यांचा शक्ती गुणक समान असतो
- तटस्थ In द्वारे प्रवाह शून्य आहे.
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 तारेमधील विद्युतप्रवाह 0A असेल
