1. Ukumelana nokuhlolwa kwe-voltage, okuvame ukwaziwa ngokuthi “isivivinyo se-voltage ephezulu ye-dielectric”, okubizwa ngokuthi “ukumelana nokuhlolwa kwe-voltage”.Umthetho oyisisekelo wokukhetha ububanzi obufanele be-voltage ukumelana nesihloli ukusebenzisa i-voltage esebenza kabili yento ezohlolwa, bese wengeza ama-volts ayinkulungwane njengezinga le-voltage yokuhlola.I-voltage yokuhlola yeminye imikhiqizo ingase ibe phezulu kuno-2 × I-voltage yokusebenza ingu-+ 1000V.Isibonelo, ububanzi be-voltage esebenzayo yeminye imikhiqizo busuka ku-100V ukuya ku-240V, futhi amandla kagesi okuhlola emikhiqizo enjalo angase abe phakathi kuka-1000V no-4000V noma ngaphezulu.Ngokuvamile, imikhiqizo enomklamo “wokufakwa kabili” ingase isebenzise amandla okuhlola angaphezu kuka-2 × Amandla kagesi asebenzayo + 1000V ajwayelekile.
2.Ukuhlolwa kwe-voltage ye-standard kunembe kakhulu ekwakhiweni komkhiqizo nasekwenzeni amasampula kunokukhiqizwa okusemthethweni, ngoba ukuphepha komkhiqizo kunqunyiwe esigabeni sokuklama nesokuhlola.Nakuba amasampula ambalwa kuphela asetshenziswa ukwahlulela ukwakheka komkhiqizo, ukuhlolwa okuku-inthanethi ngesikhathi sokukhiqiza kufanele kuqine kakhulu.Yonke imikhiqizo kufanele ikwazi ukudlula izindinganiso zokuphepha, futhi kungaqinisekiswa ukuthi ayikho imikhiqizo enesici ezogeleza iphume emugqeni wokukhiqiza.
3. I-voltage ephumayo ye-standard voltage tester kufanele igcinwe kububanzi obusuka ku-100% ukuya ku-120% wevolthi eshiwo.Imvamisa yokuphuma kwe-AC ukumelana ne-voltage tester kufanele igcinwe phakathi kuka-40Hz no-70Hz, futhi inani layo eliphakeme akufanele libe ngaphansi kwezikhathi ezingu-1.3 zevelu ye-voltage ye-root mean square (RMS), futhi inani layo eliphakeme ngeke libe ngaphezu kwezikhathi ezingu-1.5. yenani le-voltage ye-mpande mean square (RMS).
Imikhiqizo ye-4.Different inezincazelo ezahlukene zobuchwepheshe.Ngokuyisisekelo, ekuhlolweni kokumelana ne-voltage, i-voltage ephezulu kune-voltage evamile yokusebenza isetshenziswa emkhiqizweni ukuze ihlolwe.I-voltage kufanele ihlale isikhathi esithile.Uma ukuvuza kwamanje kwengxenye kugcinwa ngaphakathi kwebanga elishiwo phakathi nesikhathi esishiwo, kunganqunywa ukuthi ingxenye iphephe kakhulu ukuthi isebenze ngaphansi kwezimo ezivamile.Ukuklama okuhle kakhulu nokukhethwa kwezinto ezinhle zokuvikela kungavikela umsebenzisi ekushayweni kukagesi ngengozi
