Lub hauv paus ntsiab lus ntawm hluav taws xob ntsuas hluav taws xob
Lub induction watt teev meter yog ib hom kev ntsuas uas tuaj yeem tsim qhov kev sib hloov sib npaug rau qhov ntsuas hluav taws xob los ntawm kev sib cuam tshuam ntawm qhov tam sim no ntawm cov kauj ruaj khov thiab cov induced tam sim no nyob rau hauv lub conductive movable ib feem (feem ntau yog lub disc).
Electronic watt hour meter yog ib qho cuab yeej uas ua rau cov zis sib npaug rau qhov ntsuas hluav taws xob los ntawm kev siv tam sim no thiab qhov hluav taws xob rau khoom (Electronic) cov khoom.
Kev faib tawm ntawm hluav taws xob ntsuas hluav taws xob
Raws li cov qauv thiab cov qauv kev ua haujlwm
Mechanical zog ntsuas
Lub induction watt teev meter siv lub hauv paus ntsiab lus ntawm electromagnetic induction tig qhov voltage, tam sim no thiab theem mus rau hauv magnetic torque los tsav lub txhuas disc kom tig. Cov ncej (worm) ntawm lub disk tsav lub nruas log ntawm lub iav tsav ntsuas ntsuas kom tig. Cov txheej txheem ntawm kev sib hloov yog cov txheej txheem ntawm lub sijhawm tsub zuj zuj. Qhov zoo ntawm lub zog poob thiab tsis muaj hluav taws xob poob yog tias lub ntsuas hluav taws xob muaj zog.
