Digital single phase energy meter circuit diagram.
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.
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.
Apply a load of 2 amps by switching on the load.
Or communicate with other digital equipment.
Below are the the connections diagrams for installation of a single phase 3 phase 4 wire kwh meter digital or analog energy meter from the supply to the main distribution board in home.
Procedure for calibration and testing of single phase energy meter give the connections as per the circuit diagram above.
If the meter is inserted in the socket upside down it will in fact rotate backward and subtract apparent energy usage from the register.
