Cov cuab yeej ntsuas hluav taws xob yog cov cuab yeej tshwj xeeb uas siv rau kev kuaj xyuas, kev tshuaj xyuas, kev tshuaj xyuas, thiab kev lees paub hauv kev tsim hluav taws xob thiab kev ua haujlwm hauv kab sib chaws. Nws ua kom daim phiaj kev nyab xeeb los ntawm kev saib xyuas cov khoom siv hluav taws xob tsis zoo thiab suav nrog pawg xws li rwb thaiv tsev tiv thaiv cov khoom siv ntsuas hluav taws xob, cov khoom siv ntsuas hluav taws xob, thiab cov khoom siv tiv thaiv relay. Peb yog cov chaw tsim khoom ntawm cov khoom siv ntsuas hluav taws xob, tsim thiab tsim cov qib siab -voltage hloov cov yam ntxwv testers, cable fault testers, thiab transformer ratio testers.
Cov khoom siv no suav nrog cov khoom siv xws li lub tsev, lub hau npog sab saum toj, vaj huam sib luag pem hauv ntej, thiab lub khob roj. Qee tus qauv txhawb nqa tag nrho tsis siv neeg peb-theem kev sim, cov ntaub ntawv tswj chaw taws teeb upload, thiab siab - qhov tseeb voltage stabilization ua haujlwm. Cov khoom lag luam muaj xws li ntau-pulse cable fault testers, cais-hom DC siab-voltage generators, thiab rau -theem relay tiv thaiv testers. Peb qhov qis-voltage cable fault testers tuaj yeem ua qhov chaw rwb thaiv tsev tsis ua hauj lwm hauv av thiab nrhiav kom tau txoj hauv kev cable. Cov cuab yeej ntsuas hluav taws xob tau hloov zuj zus mus rau kev txawj ntse, miniaturization, thiab kev sib txuas lus los txhawb cov kev xav tau ntawm kev tsim vaj tsev ntse.
