Energy meter connection circuit diagram. 2 wire meter 5 va 3 and 4 wire meters 3 va per phase current circuit current circuit power consumption values. Meter a apparent power va 4 1 energy meter power consumption voltage circuit power required for the electronics in the meter is supplied via the voltage circuit. The energy meter wiring connection is same as i shown in the diagram.

Click image to enlarge. 1 shows the circuit diagram of the energy meter which is built around energy metering ic with integrated oscillator ade7757 ic1 microcontroller at89c52 ic2 eeprom at24c02 ic3 5v voltage regulator 7805 ic5 opto coupler mct2e ic4 and an lcd display. The energy meter is an integrating instrument that measures t.

Where imax 1 va. Energy meter circuit fig. In diagram i shown read yellow and blue for lines and black for neutral and shown all cables in single core but in real life use the 4 core or 4 wire cable for 3 phase kwh meter.

In the above graphics and diagrams pin incoming phase or live from the source supply voltage. However my work to provide you the wiring diagram of kwh energy meter and it s connection method. Below energy meter diagram i shown a single phase kwh meter with incoming supply and out going supply to home collage shop etc.

Single phase energy meter. In the above diagram i shown an utility pole form which i get supply to kilowatt hour e meter and after that i get supply form energy meter. The following values apply.

In the above diagram i shown utility pole from which i get connection to the meter and then get connection for load from the em.
