Igikoresho rusangi-ni igice c'ishimikiro co kugenzura gikoreshwa cane mu bijanye no kugenzura umuyagankuba. Igenzura ugufungura n’ugufunga kw’imirongo canke ama switch ashingiye ku mpinduka mu bimenyetso vy’umuyagankuba vyinjira (nk’umuriro n’umuriro) canke ibimenyetso bitari-ivy’umuyagankuba (nk’ubushuhe n’umuvuduko), bishika ku bikorwa vy’ugucungera no gukingira vyikora.
Uvuye ku ngingo ngenderwako y’ibikorwa, amarelay y’intumbero rusangi-akora canecane ashingiye ku ngingo ngenderwako y’ugutera umuyagankuba. Iyo iyo coil ifise inguvu, inguvu z’umuyagankuba zirakwegera iyo armature, bigatuma izo nzira zifunga canke zifunguka. Ku bikoresho rusangi vy'umuyagankuba, igihe co gukurura -mu bisanzwe kiva ku mirongo gushika ku majana y'amamilisegonda, kandi igihe co kurekura ni nk'ico, naho nyene agaciro kadasanzwe gashobora guhinduka bivanye n'ivyo bikoresho n'akarorero kavyo.
Ivyuma vy'intumbero rusangi-bifise ubwoko butandukanye bw'ibikoresho, harimwo ibikoresho vyuguruye, ibikoresho vyugarijwe, n'ibikoresho bihindura. Mu bisanzwe ama contacts yuguruye arafungurwa iyo relay idakora kandi agafunga inyuma yo gukora; ama contacts asanzwe yugaye arafunga iyo relay idakora kandi akafunguka inyuma yo gukora; ama contacts y’uguhindura ahuza ibikorwa vyavyo vyose, bikaba bishoboza guhindura umurongo. Mu bikorwa vy’ukuri, ubwoko bw’ugukorana bukwiye burashobora gutorwa bishingiye ku bisabwa vyo kugenzura. Igitero c’ivyuma vy’ivyuma vy’intumbero rusangi-ni ikintu gihambaye, gifise ico gikoze ku bushobozi bwaco n’ubushobozi bwo gutahura. Igitero c’ivyuma vy’umurongo mutoyi w’intumbero rusangi-biva ku majana menshi y’ama ohms gushika ku bihumbi vyinshi vy’ama ohms, mu gihe ubushobozi bwo guhangana n’ivyuma vy’umurongo w’inguvu nyinshi -buri hasi cane. Ivyo ni kugira ngo haboneke ko umuriro uhagije ushobora guca kugira ngo haboneke inguvu z’umuyagankuba zikenewe. Ugushobora guhindura ibidukikije kw’ibarabara ry’intumbero rusangi-na ryo nyene ni ngirakamaro cane; itegerezwa kuba ishobora gukora neza mu bidukikije bimwebimwe, nk’ubushuhe, ubukonje be n’uburebure bw’ikirere.
Nk’akarorero, amarelay amwe amwe y’intumbero rusangi-ashobora gukora neza mu bushuhe buri hagati ya degre -25 na degre 70 , n’ubukonje bushika hafi kuri 95%, kandi ashobora kwimenyereza uburebure bwa metero 2000 canke mbere n’ubundi. Ivyiyumviro bishizwe mu migwi hakurikijwe uko bikoreshwa, ibikoresho vy’intumbero rusangi bishobora guca mu bice bibiri: ibikoresho vy’ubugenzuzi n’ibikoresho vy’uburinzi. Ivyuma bigenzura bikoreshwa cane cane mu buryo bwo kugenzura bwikora kugira ngo hashirwe mu ngiro ubugenzuzi bujanye n’ubwenge bw’imirongo; protection relays zikoreshwa mu gukingira ibikoresho vy’umuyagankuba umuriro urenze urugero, umuriro urengeje urugero be n’umuriro muto, zigaca zica umurongo w’umuyagankuba iyo habaye ibintu bidasanzwe.
