Ramoƙar Wutar Lantarki ta Capacitor-1 (Hanyar Ƙididdigar Nauyi)

Hanyar ƙididdigar nauyin wutar lantarki tana aiki ne don tantance ƙarfin capacitor na ramoƙar wutar lantarki a cikin babban ɗakin rarraba wuta.

Wannan hanyar tana aiki ga jimillar ƙarfin nauyi na kamfani ko cibiya. Ana ninka ƙarfin da aka ƙayyade (rated power) da ma’aunin buƙata (demand factor) don samun ƙididdigar ƙarfin aiki Pj na nauyin. Sa’an nan, ana samun ƙididdigar ƙarfin ramoƙa Qj, ƙididdigar ƙarfin bayyane Sj, da ƙididdigar wutar lantarki Ij.

Muna tara Pj, Qj, Sj, da Ij na nauyin, kuma mu ninka da ma’aunin daidaituwa (simultaneity factor) don samun sigogin ƙididdiga na ɗakin rarraba wuta na taron aiki ko bene.

Bayan haka, muna tara Pj, Qj, Sj, da Ij na kowane ɗakin rarraba wuta na taron aiki ko bene, kuma mu ninka da ma’aunin daidaituwa (galibi ana ɗaukar 0.85) don samun sigogin ƙididdiga na babban ɗakin rarraba wuta.

Tunda jimillar ƙarfin nauyi na transfoma wutar lantarki galibi yana wakiltar kashi 70% na ƙarfinsa da aka ƙayyade, muna raba Sj da 0.7, muna ɗaukar mafi girman ƙima don samun ƙarfin transfoma Sn. A lokaci guda, muna amfani da Qj don samun ƙarfin ramoƙar wutar lantarki.

Muna tabbatar da cewa ƙididdigar wutar lantarki na babban na’urar katse wutar lantarki mai ƙarancin wuta (low-voltage main incoming circuit breaker) ya fi Ij girma. Ta hanyar haɗa wannan da ƙarfin transfoma Sn, ƙididdigar wutar lantarki Un, da ƙididdigar juriyar wutar lantarki Uk%, za mu iya ƙididdige wutar gajeren kewayawa Ik na transfoma, kuma ta haka mu tantance ƙarfin katsewar gajeren kewayawa Icu na na’urar katse wuta.

Ƙarfin capacitor na ramoƙar wutar lantarki, ba shakka, shine Qj.

Ƙari ga haka, idan na’urorin rarraba wuta na farko masu ƙarancin wuta da aka haɗa kai tsaye da transfoma wutar lantarki suna da kewayoyin ciyarwa (feeder circuits) kawai ba tare da kewayoyin sarrafa motoci ba, ƙarfin kewayon ramoƙar wutar lantarki yana kusan sau 0.3 zuwa 0.35 na ƙarfin transfoma.
