Isiguquli samandla wuhlobo lwesiguquli sikagesi esisetshenziswa ukudlulisa amandla kagesi phakathi kwamasekhethi amabili noma ngaphezulu ngokusebenzisa induction kagesi. Iklanyelwe ukusebenza ngama-voltage aphezulu futhi ibalulekile ekudluliselweni nasekusabalaliseni ugesi. Ama-transformer kagesi ngokuvamile atholakala eziteshini ezincane, lapho ehla khona ama-voltage aphezulu okudlulisela amandla emazingeni aphansi afanele ukusatshalaliswa ezindlini nasemabhizinisini.
Uma kukhulunywa ngamamitha wamandla,ama-transformer kagesidlala indima ebalulekile ekuqinisekiseni isilinganiso esinembile sokusetshenziswa kukagesi. Amamitha wamandla, aziwa nangokuthi ama-watt-hour metres, angamadivayisi akala inani lamandla kagesi asetshenziswa indawo yokuhlala, ibhizinisi, noma idivayisi kagesi ngokuhamba kwesikhathi. Lawa mamitha abalulekile ngezinjongo zokukhokha kanye nokuqapha ukusetshenziswa kwamandla.
Ezimweni eziningi, ikakhulukazi kuzilungiselelo zezimboni noma izakhiwo ezinkulu zezentengiselwano, amazinga kagesi angaba phezulu kakhulu ukuze amamitha wamandla ajwayelekile aphathwe ngokuqondile. Yilapho kudlala khona ama-power transformer. Zisetshenziselwa ukwehlisa amandla kagesi aphezulu ziye ezingeni eliphansi, elilawulekayo elingalinganiswa ngokuphepha imitha yamandla. Le nqubo ayivikeli kuphela imitha emonakalweni ongase ube khona ngenxa ye-voltage ephezulu kodwa futhi iqinisekisa ukuthi ukufundwa kunembile.
Ama-transformer kagesi asetshenziswa ngokuhambisana namamitha wamandla avame ukubizwa ngokuthi “ama-current transformers” (CTs) kanye “nama-voltage transformers” (VTs). Ama-transformer amanje asetshenziselwa ukukala umthamo wamanje ogeleza ku-conductor, kuyilapho ama-voltage transformer asetshenziselwa ukukala i-voltage kuyo yonke isekethe. Ngokusebenzisa lezi ziguquli, amamitha wamandla angakwazi ukubala ngokunembile ukusetshenziswa kwamandla ngokuphindaphinda amandla amanje alinganisiwe kanye ne-voltage.
Ukuhlanganiswa kwama-transformer amandla ngamamitha wamandla kubaluleke kakhulu ezinhlelweni zezigaba ezintathu, ezivame ukusetshenziswa ezimbonini zokusebenza. Kulezi zinhlelo, amasethi amathathu ama-currents nama-voltages adinga ukulinganiswa kanyekanye. Iziguquli zikagesi zisiza lokhu ngokunikeza ukwehliswa okufanele kwemingcele kagesi, okuvumela imitha yamandla ukuthi isebenze kahle.
Ngaphezu kwalokho, ukusetshenziswaama-transformer kagesikumamitha wamandla kuthuthukisa ukuphepha. Amasistimu kagesi aphezulu angadala izingozi ezinkulu, okuhlanganisa ukushaqeka kukagesi nemililo. Ngokwehlisa i-voltage ibe sezingeni eliphephile, iziguquli zikagesi zisiza ukunciphisa lezi zingozi, ziqinisekisa ukuthi kokubili imitha yamandla nengqalasizinda ezungezile isebenza ngokuphepha.
Kafushane, i-transformer yamandla iyingxenye ebalulekile ekusebenzeni kwamamitha wamandla, ikakhulukazi ekusetshenzisweni kwamandla kagesi aphezulu. Inika amandla ukukala okunembile kokusetshenziswa kukagesi ngokwehla amazinga kagesi ebangeni elilawulekayo. Lokhu akuqinisekisi kuphela ukukhokhiswa okunembayo nokuqapha ukusetshenziswa kwamandla kodwa futhi kuthuthukisa ukuphepha kumasistimu kagesi. Ukuqonda indima yeziguquli zamandla kumamitha wamandla kubalulekile kunoma ubani obambe iqhaza emkhakheni wezamandla, njengoba kugqamisa ukubaluleka kwalawa madivaysi ekusabalaliseni kahle nokuphephile kwamandla kagesi.
