Ajụjụ ndị a na-ajụkarị
Olee otú a na-ehazi voltaji kwụsịtụ?
Maka otu-phase, Vdrop = 2 × ρ × L × I / A. The factor 2 accounts for the current traveling out and back; three-phase uses √3 instead of 2.
Gịnị bụ voltaji na-akwụsị na-ekweta?
A na-emekarị iwu nke thumb bụ ka ịnagide zuru ezu drop n'okpuru 3% maka branch circuits na 5% zuru ezu. N'ebe dị ukwuu conductors (n'ebe dị ukwuu) na-abawanye drop.
Copper mọọbụ aluminum - ọ bụ ihe dị mkpa?
Ee. Aluminum nwere ihe dịka 60% elu resistivity karịa copper, ya mere aluminum na-agba ọsọ nke otu nha na-apụ n'ụzọ dị iche iche karịa voltaji.
Gịnị mere fomulụ ji jiri ogologo abụọ?
Current nwere ike na-agafe n'ime na-ebu na azụ, ya mere a single-phase circuit na-ahụ na-apụ nke abụọ conductors - ya mere ihe kpatara nke 2 × ogologo. Three-phase circuits iji √3 (n'ihe banyere 1.732) na-ebe, na-egosi na geometric nke balanced three-phase ike.
Olee otú m ga-esi belata nkwụsị nke voltaji?
