Power system ni hta n-gun shadawn na matu madung jak rai langai hku nna, three-phase energy meter ni a hpaji masa rawt jat wa ai gaw, grid bungli galaw ai lam a kam hpa mai ai lam hte sut masa lam hpe hkrak hkra hkra machyi shangun nga ai. Kade nna ai aten hta, smart grids ni rawt jat wa ai, n-gun npawt nhpang nnan ni hpe hpawng de wa ai, n-gun atsam gat lawk hpe gram lajang wa ai majaw, three-phase energy meter ni gaw hkrak ai lam, bungli galaw ai lam hpe hpawng de ai lam, matut mahkai ai atsam ni hta grai rawt jat wa sai.
Metering hkrak ai lam hte seng nna, htunghking wan n-gun 3-phase n-gun meter ni hpe electronic meter ni hte loi loi hte galai shai wa nga ai. Electronic meter ni gaw, grai hkrak ai analog{3}}to-digital galai shai ai jak ni hte digital signal galaw ai hpaji masa ni hpe jai lang ai majaw, shadawn shadang shut ai lam ni hpe 0.1% laman hta hkang lu ai, 0.5%-2% hta grau law ai. Dai hta n-ga, mungkan madang (IEC 62053 zawn re ai) ni gaw, 3-phase energy meter ni a hkrak ai madang ni hpe grai sadi maja let hkang da ai majaw, circuit design hte calibration ladat ni hpe grau kaja hkra galaw na matu, galaw shapraw ai ni hpe shadut ya nga ai.
Functional hku hpawng de ai lam gaw kaga ahkyak ai lam langai mi rai nga ai. Dai ni na aten na three-phase n-gun shadawn ai jak ni gaw, n-gun shadawn ai lam a madung bungli ni hpe galaw ya ai sha n-ga, harmonic sawk sagawn ai lam, voltage sag hpe sawk sagawn ai lam, load profile hpe ka matsing ai lam zawn re ai rawt jat galu kaba wa ai atsam ni hpe mung hpawng de da ya ai. Ga shadawn, high-end wan n-gun meter nkau mi gaw, aten dep 3-phase n bung ai hpe yu maram lu nna, phase n bung ai majaw byin pru wa ai meter shut ai lam ni hpe gram lajang na matu algorithms ni hpe jai lang lu ai. Dai hta n-ga, Microprocessor hte embedded system ni hpe jai lang ai majaw, wan n-gun meter ni gaw buga na data ni hpe galaw lu nna, garan gachyan ai n-gun hpe hparan ai lam hpe madi shadaw ya lu ai.
Matut mahkai hpaji rawt jat wa ai majaw, three-phase wan n-gun meter ni a hpaji hpe grai jat wa shangun ai. Power line carrier (PLC), radio frequency (RF), hte fiber optic matut mahkai lam ni hpe madung tawn nna tsan tsan kaw na meter hti ai ladat ni gaw, aten tengman ai-data shiga ni hpe htawn shalai ai lam hte tsan tsan kaw nna hkang lu ai lam ni hpe madi shadaw ya ai. Kade nna ai aten hta, narrowband Internet of Things (NB-IoT) hte 5G hpaji masa ni hpe jai lang wa ai majaw, matut mahkai lam hpe grau shayawm ya lu nna, wan n-gun grid a shamu shamawt ai lam hpe grau jat wa shangun ai. Dai hta n-ga, n-gun ja ai network shimlam hpaji masa ni (encryption algorithms hte identity authentication zawn re ai ni) gaw, metering data ni hpe n-gun jaw ai lam hte n-gun jaw ai lam ni hpe n-gun jaw ya ai.
Htawm hpang na sawk sagawn ai lam ni hta, three-phase wan n-gun meter ni hta, grau tsaw ai-htuk manu ai sensor hpaji masa, n-gun law law hpe shingdaw nna shadawn ai (ga shadawn, wan n-gun, katsi ai, wan n-gun n-gun masa ni hpe hpawng de da ai), AI-driven fault hpe tau hkrau tsun shapraw ai lam ni hpe madung tawn na re. Mungkan ting na n-gun atsam garan ginhka ai lam galai shai wa ai hte maren, three-phase wan n-gun meter ni gaw grau kam hpa mai ai lam, bungli law law galaw lu ai lam, hte networking ni de matut nna rawt jat wa nna, smart grids ni hpe digitalization galaw na matu npawt nhpang hpe gaw gap ya na re.
