Electromechanical KWh Meter -Hour Meters-How Smart Meters Work

567

Smart meters are advanced measurement devices based on modern communication technology, computer technology, and measurement technology that collect, analyze, and manage electrical energy information data. The basic principle of smart meters is: rely on A / D converters or metering chips to collect real-time user current and voltage, and carry out analysis and processing through the CPU to realize the calculation of forward, reverse, peak, valley, or four-quadrant energy, and further convert the amount of electricity. Output via communication, display, etc.

 

The composition and working principle of electronic smart meters are very different from traditional inductive energy meters.

Inductive electric meters are mainly composed of aluminum plates, current and voltage coils, permanent magnets and other components. Their working principle is mainly measured by the interaction between the current coil and the eddy current induced in the movable lead plate. The electronic smart electric meter is mainly composed of electronic components. Its working principle is to first sample the user's power supply voltage and current in real time, and then use a dedicated electric energy meter integrated circuit to process the sampled voltage and current signal and convert it into The pulse output proportional to the electric energy is finally processed and controlled by the single-chip microcomputer to display the pulse as power consumption and output.

 

Usually we call the number of pulses sent by the A / D converter when the smart meter measures one degree of electricity as a pulse constant. For smart meters, this is a more important constant because the A / D converter is in unit time The number of pulses sent will directly determine the accuracy of the meter.
