Bungli galaw ai tara hku nna garan ginhka ai
1. Hpaji hte shadawn ai (Induction shadawn ai)
Mechanical meter ni gaw shawng nnan na wan n-gun hpe shadawn ai jak rai ni rai nna, wan n-gun hpe n-gun dat ai (electric induction) ngu ai npawt tara hte bungli galaw ai. Current hte voltage coil ni kaw na pru wa ai magnetic field gaw aluminum disk hpe shinggrup na matu shadut ya nna, shinggrup ai lawan ai lam gaw n-gun jai lang ai hte maren sha rai nga ai. Ndai shinggrup ai lawan ai lam hpe hpang jahtum e gear train langai mi gaw digital dial hpe madun na matu shachyut ai. Ndai zawn re ai meter gaw asan sha rai nna-manu n law ai raitim, hkrak ai lam n law ai hte tsan tsan kaw nna data hpe n mai htawt sit ai majaw tsin-yam hkrum nga ai. Dai majaw, loi loi hte electronic meter ni hte galai shai wa nga ai.
2. Elektronik hte shadawn jak
Electronic meter ni gaw, n-gun lang ai lam hpe hkrak sha sawn la nna, digital display ntsa hta data ni hpe madun dan na matu, electronic circuit ni hpe (analog-to-digital galai shai ai jak ni hte Microprocessor ni zawn re ai ni hpe lang ma ai. Mechanical meter ni hte shingdaw yu yang, shanhte gaw grau hkrak ai (0.2S madang du hkra), grau n-gun ja ai-hkap la lu ai atsam, -lang ai aten-billing hte kaga magam bungli ni hpe madi shadaw ya lu ai. Ya aten hta shanhte gaw nta hte bungli galaw ai shara ni hta jai lang ai meter ni a madung ladat rai nga ai.
3. Hpaji rawng ai meter ni
Smart meter ni gaw, electronic meter ni hpe gram lajang da ai version ni re. Shanhte gaw matut mahkai module ni hpe (LoRa, NB-IoT shing nrai wan n-gun line htaw ai ni zawn re ai ni) hpawng de nna, tsan tsan kaw nna shi hkum shi meter hti lu ai, tengman ai-ten hpe yu reng lu ai hte -lam lahkawng hku matut mahkai lu ai. Wan lang ai ni gaw mobile phone apps hku nna wan n-gun lang ai lam hpe yu mai ai, wan n-gun grid company ni mung wan n-gun jaw ai ladat ni hpe n-gun ja ai hku galai shai mai ai. Shanhte gaw smart grids ni a madung daw ni rai nga ai.
Jai lang ai hku nna garan ginhka ai
1. Langai -phase meter ni
Nta ni (sh) hpaga yumga galaw ai shara kaji ni hta single-phase AC power shadawn na matu lang ai. 220V voltage makau grup yin hta law malawng lang ai, shadawn shadang gaw 5 (60) A (sh) 10 (40) A rai nna, general lighting, nta na arung arai ni, etc. ni a load ra kadawn ai lam ni hpe hkap la lu ai.
2. Masum-phase meter
Industrial (sh) hpaga lam kaba hta jai lang ai ni a matu galaw da ai, 380V masum-phase power system ni a matu htuk manu ai, masum-phase masum-wire (neutral wire n lawm ai) hte masum-phase mali-wire (neutral wire lawm ai) ngu nna lahkawng garan nna galaw da ai. Hpaji rawng ai hkrang masa ni gaw, n-gun ja ai jak ni, transformer ni hte kaga jak ni a n-gun lang ai lam hpe shadawn lu nna, hkrang masa nkau mi gaw harmonic analysis hpe madi shadaw ya ai.
3. Shawng jaw da ai Meter ni
Electronic hpaji hpe IC card (sh) tsan tsan kaw nna gumhpraw bang ai ladat ni hte kayau kaya galaw nna, wan n lang shi yang, shanhte a account hta gumhpraw bang ra ai.

Install galaw ai ladat hku nna garan ginhka ai
1. Meter hpe hkrak-matut u
Current line gaw load hte hkrak matut da ai, current n law ai application ni a matu htuk manu ai (ga shadawn<=100A). Ndai asan sha re ai hkrang masa gaw, n-gun kaba ai n-gun ni a matu, n-gun galai shai ai transformer ra ai.
2. Galai shai ai jak-Meter hpe matut mahkai na
Hpa majaw nga yang, n-gun kaba ai -voltage (sh) n-gun kaba ai-n-gun (substation zawn re ai) ni hpe n-gun galai ai (CTs) hte n-gun galai ai (PTs) hku nna matut mahkai ai. Meter gaw n-gun n law ai-power signal ni hpe sha galaw ya ai majaw, shim lum lam hte shadawn shadang hpe jat mai ai.
Data htawt sit ai ladat hku nna garan ginhka ai
