Audluliseingxenye ye-elekthronikhi esebenzisa izimiso zozibuthe kagesi noma eminye imiphumela ebonakalayo ukuze kuzuzwe “ukukhanyisa/ukuvala okuzenzakalelayo” kwamasekhethi. Umsebenzi wayo oyinhloko ukulawula ukucishwa kwamasekhethi amakhulu wamanje/aphezulu anamasignali amancane/amasignali, kuyilapho futhi kuzuzwa ukuhlukaniswa kukagesi phakathi kwamasekhethi ukuze kuqinisekiswe ukuphepha kokuphela kokulawula.

Imisebenzi yayo eyinhloko ingahlukaniswa ngezigaba ezintathu:

1. Ukulawula Nokukhulisa: Ingakwazi ukuguqula amasignali okulawula abuthakathaka (njengama-currents ezinga le-milliampere ngamakhompiyutha amancane nezinzwa) abe amaza anamandla anele ukushayela amadivayisi anamandla amakhulu (njengamamotho namahitha), asebenza “njengesikhulisamandla sesiginali”. Ngokwesibonelo, ezindlini ezihlakaniphile, amasignali amancane kagesi athunyelwa izinhlelo zokusebenza zefoni ephathekayo angalawulwa ngokusebenzisa ama-relay ukuze avule futhi acime amandla ezifudumezi zomoya kanye namalambu.

2. Ukuhlukaniswa kukagesi: Alukho uxhumano lukagesi oluqondile phakathi kwesifunda sokulawula (i-voltage ephansi, yamanje encane) kanye nesifunda esilawulwayo (i-voltage ephezulu, yamanje enkulu). Iziqondiso zokulawula zidluliselwa kuphela ngamasignali kazibuthe noma optical ukuvimbela amandla kagesi aphezulu ukuthi angangeni kutheminali yokulawula futhi alimaze okokusebenza noma abeke engcupheni ukuphepha kwezisebenzi. Lokhu kuvame ukutholakala kumasekhethi okulawula amathuluzi omshini wezimboni nezinto zamandla.

3. I-Logic and Protection: Ingahlanganiswa ukuze kusetshenziswe i-logic yesifunda esiyinkimbinkimbi, njengokuhlanganisa (ukuvimbela amamotho amabili ukuthi aqale ngesikhathi esisodwa) nokulawula ukubambezeleka (ukubambezela ukuxhuma komthwalo isikhathi esithile ngemva kokukhanyisa amandla). Okunye ukudluliselwa okuzinikele (okufana nokudluliswa kwe-overcurrent kanye ne-overheating relay) nakho kungaqapha ukungahambi kahle kwesekethe. Uma i-curse inkulu kakhulu noma izinga lokushisa liphezulu kakhulu, bazonqamula isekethe ngokuzenzakalelayo ukuze bavikele izinto zikagesi ekulimaleni kokugcwala kakhulu.
