Kev Npaj Theem:
Fais fab Off Detection: Xyuas kom lub cable yog powered (lub hwj chim tawm yog yuav tsum tau rau rwb thaiv tsev tiv thaiv kev ntsuam xyuas).
Kev Tiv Thaiv Kev Nyab Xeeb: Hnav cov hnab looj tes insulated thiab tsom iav, thiab siv cov cuab yeej insulated.
Cov Khoom Siv Calibration: Txheeb xyuas lub zog thiab ntsuas cov xwm txheej ntawm cov cuab yeej ntsuas (xws li clamp meters thiab thermal imagers).
Kev Xeem Phaj:
Rwb thaiv tsev Resistance Test: Txuas cov tester electrodes rau cable conductor thiab sheath, siv voltage, nyeem tus nqi kuj, sau cov ntaub ntawv, thiab muab piv nrog tus qauv.
Leakage Current Detection: Clamp lub clamp meter rau hauv av xaim thiab saib seb tus nqi tam sim no puas ruaj khov. Yog tias qhov kev hloov pauv ntau dua 10%, xav tau kev tshawb nrhiav ntxiv.
Infrared Thermal Imaging Detection: Tshawb xyuas tag nrho qhov ntev ntawm lub cable, tsom rau thaj chaw uas muaj cua sov tsim xws li cov pob qij txha thiab khoov. Rov kuaj dua yog tias qhov ntsuas kub tsis zoo.
Phase tsom xam:
Cov ntaub ntawv sib piv: Sib piv cov txiaj ntsig kev xeem nrog cov ntaub ntawv keeb kwm lossis cov qauv kev lag luam los txiav txim siab txog qib kev pheej hmoo ntawm kev xau.
Leakage Point Qhov Chaw: Muab ntau txoj hauv kev (xws li kev tso tawm ib nrab + infrared thermal imaging) txhawm rau txheeb xyuas qhov to kom raug.
Theem Kev Kho Mob:
Kho lossis Hloov Kho: Kho lossis hloov tag nrho cov cable nrog cov rwb thaiv tsev puas.
Retesting thiab Verification: Rov qab kuaj dua tom qab kho kom ntseeg tau tias qhov teeb meem xau tau daws tiav.
