Digital Single Phase Energy Meter Circuit Diagram

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.

Digital single phase energy meter circuit diagram.

Three phase energy meter. A single phase energy meter prototype has been implemented in the lab to provide measurement up 10 a load current from a 127 v line voltage. Electromechanical energy meters have been the standard for metering the electricity since billing began. Apply 220v a c to the pressure coil circuit by means of phase shifting transformer.

Apply a load of 2 amps by switching on the load. The observed accuracy was better than 97 discover the. Can read up to 999999 units kwh with a resolution of 0 01 units 2. Single phase electricity explained.

But these are now being gradually replaced by electronic digital energy meters. Note down the reading of two meters in a given period of time say 2 minutes. Image extraction ie approach to extract information from analog and digital kwh meters. Single phase energy meter pt ct meter 3.

Or communicate with other digital equipment. Procedure for calibration and testing of single phase energy meter give the connections as per the circuit diagram above. Its salient features are. 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.

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. If the meter is inserted in the socket upside down it will in fact rotate backward and subtract apparent energy usage from the register. Would you please send me the circuit diagram of your energy meter using ade7753. Regarding the hardware.

The red wire shows the live or line or phase and the blake shows the neutral wire. Design and building a single phase smart energy meter. 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. In a typical residential single phase meter form 2s type the upper two lugs are connected to utility source and lower lugs are connected to the house branch circuit panel.
