Amasokhethi ekhebula lamandla kagesi aphezulu (HV).ukudlala indima ebalulekile ezinhlelweni zokudluliswa kwamandla kanye nokusabalalisa. Lawa masokhethi aklanyelwe ukuxhuma ngokuphepha nangempumelelo izintambo zikagesi ophezulu ezinhlobonhlobo zezinto zikagesi ezifana nama-transformer, ama-switchgear nama-circuit breaker. Ngaphandle kwezitolo zekhebula ezinokwethenjelwa nezisezingeni eliphezulu, ubuqotho nokusebenza kahle kwalo lonke uhlelo lukagesi kungaba sengozini.
Omunye wemisebenzi eyinhloko yamasokhethi ekhebula lamandla kagesi aphezulu ukuhlinzeka ngoxhumano oluphephile noluvalekile ezintamboni zamandla kagesi aphezulu. Lezi zindawo zokuphuma ziklanyelwe ngokukhethekile ukuphatha ama-voltage aphezulu kanye nesici semisinga yamasistimu kagesi anamandla amakhulu. Ngokuhlinzeka ngoxhumano oluphephile noluthembekile, izintambo ezinamandla kagesi zisiza ukunciphisa ingozi yamaphutha kagesi, ama-arcs, namasekhethi amafushane angaholela ekunqamukeni kukagesi, ukulimala kwemishini, ngisho nezingozi zokuphepha.
Ngaphezu kokuhlinzeka ngoxhumano lukagesi oluphephile, amasokhethi ekhebula ane-voltage ephezulu adlala indima ebalulekile ekusizeni ukudluliswa kwamandla ngendlela efanele. Ngokusebenzisa izinto zokufakelwa ezithuthukisiwe kanye nobuchwepheshe bokuklama, amasokhethi ekhebula lamandla kagesi aphezulu anganciphisa ngempumelelo ukulahlekelwa kwamandla futhi aqinisekise ukuthi inani eliphezulu lamandla lifinyelela lapho liya khona. Lokhu kubaluleke kakhulu ezinhlelweni zokudlulisa amabanga amade, lapho ngisho nokulahlekelwa okuncane kungase kube nomthelela omkhulu ekusebenzeni kahle kwesistimu yamandla.
Esinye isici esibalulekile samasokhethi ekhebula lamandla kagesi aphezulu yikhono lawo lokumelana nezinselelo zemvelo nokusebenza okukhona ezinhlelweni zokudlulisela nokusabalalisa. Lezi zimpahla zivame ukufakwa ngaphandle noma ezindaweni eziqinile zezimboni, lapho zichayeka khona ezingeni lokushisa elidlulele, umswakama, kanye nengcindezi yokusebenza kwemishini. Ngakho-ke, amasokhethi ekhebula le-voltage ephezulu kufanele abe nesibindi, ngezinga eliphezulu lokuvikelwa kokungena kanye nokumelana nezici zemvelo ukuze kuqinisekiswe ukwethembeka nokusebenza isikhathi eside.
Ukwengeza, amasokhethi ekhebula aphezulu-voltage ayingxenye ebalulekile yokusebenza okuphephile nokusebenza kahle kwemishini yamandla aphezulu. Ngokuhlinzeka ngoxhumano oluphephile noluvaleleke, lezi zitolo zisiza ukunciphisa ubungozi bezingozi zikagesi futhi ziqinisekise ukuphepha kwabasebenzi bezokulungisa kanye nabanye abasebenzi abangase bahlangane nesistimu kagesi. Ukwengeza, ukusebenzisa amasokhethi ekhebula ekhwalithi ephezulu kungasiza futhi ukuthuthukisa ukwethembeka okuphelele nokutholakala kwesistimu yamandla, kunciphise amathuba okunqamuka kukagesi okungalindelekile kanye nesikhathi sokuphumula.
Ngokufigqiwe,amasokhethi ekhebula lamandla kagesi aphezuluyizingxenye ezibalulekile zezinhlelo zokudluliswa nokusabalalisa amandla. Ngokuhlinzeka ngoxhumano oluphephile nolusebenzayo kuzintambo ezinamandla kagesi, lezi zitolo zisiza ukuqinisekisa ubuqotho, ukusebenza kahle nokuphepha kwesistimu kagesi. Lapho ukhetha isokhethi yekhebula lamandla kagesi aphezulu wohlelo oluthile, kubalulekile ukucabangela izici ezifana nezilinganiso zamandla kagesi kanye nezamanje, izakhiwo zokuhlukanisa, ukuvikelwa kwemvelo kanye nokuhambisana nezindinganiso nemithethonqubo efanele. Ngokukhetha izintambo ezifanele ze-high-voltage futhi uzifake ngendlela efanele, opharetha besistimu yamandla bangasiza ukukhulisa ukusebenza nokuthembeka kwengqalasizinda yabo.
