Olsem wanpela bikpela samting bilong skelim eneji konsumsen insait long ol singel-feis AC seket, ol singel-feis eneji mita i save bungim ol 'electromagnetic induction', 'electronic measurement', na 'precision mechanical transmission' teknoloji. Long rot bilong 'scientific structurel design', ol i save kisim stretpela skelim bilong eneji.
Ol tradisenel 'electromechanical single-phase energy meters i save wok bihainim lo bilong 'electromagnetic induction'. Taim ol i givim 'load current' na 'voltage' long 'current coil' na 'voltage coil', ol i save kamapim 'alternating magnetic flux' long 'aluminium turntable'. Folem prinsipol bilong Faraday long 'electromagnetic induction', senis bilong 'magnetic flux' i save kamapim ol 'eddy currents' insait long 'turntable'. Wok bung bilong ol 'eddy currents' na 'magnetic flux' i save kamapim wanpela 'driving torque', na i save kirapim 'turntable'. Long wankain taim, 'constan magnetic field' we 'braking magnet' i kamapim i save katim ol 'magnetic lines of force' bilong muvmen bilong 'turntable', na kamapim wanpela 'braking torque' we i wankain olsem 'rotational speed'. Long pinis bilong en, dispela i mekim na spit bilong 'turntable' i stret wantaim 'load power'. Wanpela 'gear transmission mechanism' i save senisim 'rotational speed' bilong 'turntable' i go long 'meter reading', na dispela i mekim na ol i ken skelim 'cumulative energy'.
Ol ilektronik singel-feis eneji mita bilong nau i yusim wanpela haibrid analog-dijitel disain. Dispela 'voltage sampling circuit' i yusim wanpela 'resistor divider network' long kisim wanpela liklik signal we i stret long 'input voltage'. Karent sampling i yusim wanpela manganese-kopa shunt o karent trensfoma long senisim bikpela karent i go long liklik signal. Bihain long ol i senisim ol analog voltej na karent signal i go long ol dijitel veliu long rot bilong wanpela analog-i go long-dijitel konveta (ADC), wanpela maikrokontrola (MCU) i save mekim ol 'real-taim kalkulesen bihainim 'instantaneous power equation' (P=UIcosφ) na i yusim wanpela 'accumulation algorithm' long kalkuletim eneji veliu. Ol bikpela 'circuitry' i gat wanpela 'high-precision 'reference source' bilong mekim 'sampling' i kamap stret, wanpela 'low-pass filta bilong rausim 'high-frequency interference', na wanpela 'digital signal processor' (DSP) bilong mekim wok bilong kompyuta i kamap gutpela moa.
Kompensesen bilong ol asua em i wanpela bikpela hevi bilong disain: wanpela tempereja kompensesen seket i stretim ol samting we i save kamap long ol samting bilong 'resistor', ol i yusim ol 'phase compensation' teknik long rausim ol 'fase' we i no wankain long 'voltage' na 'current sampling channels', na ol i yusim ol 'software algorithm' long stretim ol 'light-load characteristics' na 'linearity deviations'. Anti-krip disain i yusim magnetik fluks kompensesen insait long voltej seket o ilektronik zero-karent diteksen long stopim rong skelim long taim bilong no-lod kondisen.
Wantaim divelopmen bilong ol smat grid, ol nupela singel-feis eneji mita i wok long bungim ol wayales komyunikesen modul, sekyuriti enkripsen sip, na ol multi-reit mita kapabiliti. Taim ol i holim yet ol as tingting bilong mita, ol i wok long kamap gutpela na gutpela wok.
