Last time i write about the single phase EM wiring and in this post i am writing about the 3 phase kwh meter wiring and its connection diagram.As you know that we use two types of electrical appliances regarding its rated voltage, in which some are for single phase and some are required 3 phase, just like this we use two types of kWh meter in which one for single phase and 2nd kWh meter 3 phase.
In single phase supply mostly we use 110 or 220 and in three phase our voltage 380 to 440v.
In this post i am writing about three phase kwh meter wiring connection which is too simple wiring connection and also its instillation is too simple but only for professionals because in in single phase power source we have one neutral and one phase and in three phase 4 wire system we have 3 phase w hich manse the dangerous is more then two time form single phase power source.
Just lick this we use red, Yellow, blue for three phase and red yellow blue and black for 3 phase 4 wire system.
In single phase kwh meter we have 4 terminal in which the first one for incoming phase wire which is come form the main distribution utility pole and 2nd one for neutral which is also come from the main distribution pole, the 3rd thermal for out going N and the last one is for out connection of phase to load.
As in single phase kwh m eter wiring we have 2 connection points for incoming and 2 for connection points for out going just lick this in 3 phase kwh meter wiring we have 4 connection points for incoming and 4 for out going connection.
For single phase we use the 2 core wire, for 3 phase we use 3 core wire and for three phase 4 wire system we use the 4 core electric cable.
As we know that the 3 phase kwh energy meter is design for three phase 4 wire system, so we use the 4 core electric cable for this, however in the diagram i will show single core cables form which you can learn easily.
In the above diagram i shown how to wire or instill the three phase energy meter. In the above diagram i shown cable in single single core for your better understanding, in real life we reconnected 4 core electric cable for the 3 phase energy meter instilling.
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.
The energy meter wiring connection is same as i shown in the diagram.
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 phasekwh meter. If the 4 core electric cable is not available you can also use the single core cables or double core cables but the best option to use the 4 core cable.
I hope know you understand the complete process of kwh meter 3 phase wiring and instillation, one thing more that the method of wiring of analog and digital three phase energy meter is same.
In single phase supply mostly we use 110 or 220 and in three phase our voltage 380 to 440v.

3 Phase KWh Meter Wiring Complete Guide
As you know that we use different colors of wires for different substance and places. For single phase we use two colors which red and black. Black for neutral and the Red for phase or Line.Just lick this we use red, Yellow, blue for three phase and red yellow blue and black for 3 phase 4 wire system.
In single phase kwh meter we have 4 terminal in which the first one for incoming phase wire which is come form the main distribution utility pole and 2nd one for neutral which is also come from the main distribution pole, the 3rd thermal for out going N and the last one is for out connection of phase to load.

For single phase we use the 2 core wire, for 3 phase we use 3 core wire and for three phase 4 wire system we use the 4 core electric cable.

Three / 3 phase kwh meter wiring diagram
In the above diagram i shown how to wire or instill the three phase energy meter. In the above diagram i shown cable in single single core for your better understanding, in real life we reconnected 4 core electric cable for the 3 phase energy meter instilling.
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.
The energy meter wiring connection is same as i shown in the diagram.
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
I hope know you understand the complete process of kwh meter 3 phase wiring and instillation, one thing more that the method of wiring of analog and digital three phase energy meter is same.
