Single Phase Electronic Energy Meter Circuit Diagram

The voltage and currents of the power line are rated down to signal level using transducers like voltage and current transformers and given to that ic as shown in the figure.

Single phase electronic energy meter circuit diagram. Here are ten simple electric circuits commonly found around the home. A simple capacitive power supply for the msp430 energy meter appropriate values of resistor r22 and capacitor c49 are chosen based on the required output current drive of the. The meter which is used for measuring the power of three phase supply is known as the three phase energy meter the three phase meter is constructed by connecting the two single phase meter through the shaft. Figure 3 shows a simple capacitor power supply for a single output voltage of 3 3 v directly from the mains voltage of 110 220 vrms alternating current ac.

The total energy is the sum of the reading of both the elements. The energy is the total power consumed and utilised by the load at a particular interval of time it is used in domestic and industrial ac circuit for measuring the power consumption. But these are now being gradually replaced by electronic digital energy meters. The electric main supply 230v ac 120v ac in us is connected through secondary of the transformer 3 phase 4 wire system single phase energy meter and mcbs dp sp to sub circuits and final sub circuits to protect all the connected electrical devices and appliances through electrical wiring installation.

The connection and circuit diagram of single phase 3 phase 4 wire kwh meter digital or analog energy meter from the supply to the main distribution board in the above graphics and diagrams p in incoming phase or live from the source supply voltage. 3 phase electronic energy meter. The meter is less expensive and accurate. The meter which is used for measuring the energy utilises by the electric load is known as the energy meter.

In this post i only share with you diagram in which i shown the complete method of energy meter wiring or instillation. Electromechanical energy meters have been the standard for metering the electricity since billing began. It uses ad7755 a single phase energy measurement ic to acquire and process the input voltage and current parameters. Presented here is a simple energy meter using analog device s ade7757 chip for single phase 2 wire phase and neutral systems used in households.
