Ma’aunin Ƙarfin Wutar Lantarki-2 (Ma’aunin Ƙarfin Wutar)

1. Ƙididdigewa da tabbatar da ma’aunin wutar lantarki $\cos \Phi$:

(Formula 1)

Inda:

$P$— Ƙididdigar wutar aiki mai aiki na kamfani

$Q$— Ƙididdigar wutar aiki mara aiki na kamfani

$\alpha$, $\beta$— Matsakaicin shekara-shekara na nauyin wutar aiki mai aiki da mara aiki, inda $\alpha$ yake daga 0.7 zuwa 0.75, kuma $\beta$ ana ɗauka a matsayin 0.76.

Bayan gyara ta wucin gadi, ma’aunin wutar lantarki na nauyin da aka ƙididdige ya kamata ya kasance sama da 0.9.
