Doorashada ku habboonwareegga wareeggawaxay u baahan tahay qiimayn dhamaystiran oo ku saabsan xuduudaha wareegga, sifooyinka rarka, deegaanka rakibaadda, iyo shuruudaha ilaalinta. Tixgelinta asaasiga ah ayaa hubinaysa in korantada la qiimeeyay ay la mid tahay korantada nidaamka, hadda la qiimeeyay ayaa ka weyn culeyska hadda jira, laakiin ka yar awoodda hadda-qaadista, iyo awoodda jebinta (Icu) waxay ka sarreysaa hadda la filayo gaaban gaaban.
Xulashada Halbeegga Furaha
Voltage La qiimeeyay: Waa in uu ahaado ≥ khadka lagu qiimeeyay danab (tusaale, inta badan loo isticmaalo guryaha 220V/380V). Korontada sii daynta hooseysa waa in ay la socotaa tamarta nidaamka.
Hadda la qiimeeyay:
Xisaabi inta ugu badan ee hadda shaqaynaysa culayska (Ib). Dooro awareegga wareeggaleh xawaal lagu qiimeeyay (In) oo buuxiya shuruudaha soo socda: Ib < In ≤ kirishboyga awoodda hadda-qaadista badbaado leh (tusaale, 6mm² silig naxaas ah ayaa leh awoodda hadda-qaadeysa ee ku dhawaad 40A, dooro ≤40A wareegtada wareegga).
Waa in uu ka weynaadaa inta ugu badan ee laynka la filayo in uu hadda wareeg-gaaban yahay (Ik), kaas oo lagu xisaabin karo iyadoo la isticmaalayo qaacidooyin ama iyadoo la tixraacayo miisaska (tusaale, awoodda beddelka ee 1600kVA, Ik≈38.5kA). 3
