I-fuse yomkhawulo wamanje we-voltage ephezulu yokuvikela i-transformer

Ingasetshenziswa ohlelweni lwangaphakathi lwe-50Hz kanye ne-voltage elinganisiwe engu-12kV, Isetshenziswa kanye nezinye izinsiza zokushintsha ezifana nokushintsha kokulayisha, ama-vacuum contactors, ingavikela ama-transformer kagesi kanye nezinye izinsiza zikagesi ekucindezelweni ngokweqile noma kwi-short circuit. Futhi iyisengezo esidingekayo sebhokisi lokushintsha elinamandla aphezulu, ikhabhinethi yesekethe eyindilinga, isiteshi esincane se-transformer esithwala phezulu esinomthamo ophezulu/ophansi.
