Ukuhlola okuvimbelayo kwephepha-izintambo ezivalekile nezenjoloba-zepulasitiki{2}}izintambo ezivalekile ngokuvamile zibandakanya ukumelana nokufakwa kwe-insulation kanye nokuhlolwa kwamandla kagesi.
Lapho uhlola ukumelana nokufakwa kwekhebula, sicela uqaphele okulandelayo:
I-1) Indlela yokulinganisa ukumelana nokwehlukanisa ifanele izintambo ezinobude obulinganiselwe. I-megohmmeter ngokuvamile isetshenziselwa ukukala nokubala isilinganiso sokumuncwa. Ngaphansi kwezimo ezifanayo zokuhlola, ngcono i-insulation yekhebula, isilinganiso sokumuncwa siphezulu.
2) Ngokuvamile ayikho imithetho ethile yamanani okumelana nokufakwa kwentambo. Isimo se-insulation sekhebula kufanele sinqunywe ngokuqhathanisa namarekhodi okuqala. Ngenxa yokuthi izinga lokushisa lithinta ukumelana nokufakwa kwekhebula, izimo zezulu ezifana nezinga lokushisa lomoya kanye nomswakama kufanele zirekhodwe ngesikhathi sokuhlolwa kokufakwa kwekhebula ngezinjongo zokuqhathanisa.
3) I-Megohmmeter Ezosetshenziswa: Kuzintambo ezinezintambo ezingaphansi kuka-1 kV, sebenzisa i-500-1000 V megohmmeter; kumakhebuli anama-voltage angu-1 kV nangaphezulu, sebenzisa i-megohmmeter engu-1000-2500 V.
4) Ngaphambi kokuhlolwa, ikhebula kufanele likhishwe ngokuphelele futhi libekwe phansi ngokubeka phansi i-conductor core kanye nomgodla wensimbi wekhebula.
5) Ngaphambi kokuhlola, hlanza ingaphezulu lomkhono wetheminali yekhebula ukuze unciphise ukuvuza kwendawo. Sebenzisa enye inkaba yekhebula evalekile njengeluphu evikelayo. Xhuma amakhondatha kuzo zombili iziphetho zalo mgogodla ovalekile kumkhono noma ukufakwa kwe-insulation ye-insulated core ehlolwa ngentambo yensimbi eguqukayo, uwasonge izikhathi ezimbalwa ngaphambi kokuwaxhuma kumatheminali ehawu e-megohmmeter.
6) Ngemuva kwesilinganiso ngasinye sokumelana nokufakwa, khipha futhi ugaye ikhebula. Uma ikhebula liba lide, kuba ngcono isimo se-insulation. Isikhathi sokumisa kufanele sibe side, ngokuvamile okungenani umzuzu owodwa.
I-DC ukumelana nokuhlolwa kwe-voltage ukuhlola okuyisisekelo kakhulu kokunikezwa kwephrojekthi yekhebula noma ukuhlolwa kokuvimbela, futhi kuyisisekelo esiyisisekelo sokunquma ukuthi intambo yekhebula ifaneleka yini ukusebenza. Izintambo ezisebenzayo kufanele zihlolwe njalo nge-DC, futhi ukuvuza kwamanje kufanele kulinganiswe.
