- Find out how to wire 3 phase power meter to measure current, voltage, power, power factor, frequency, energy, THD etc.
It is panel mounted multifunction meter but in similar way you can connect any other type of multifunction meters.

What do you think about this video ?
Suprisingly helpful, thank you
Great Video, super helpful
THANKS A LOT SO HELPFUL .
Useful !
Very good video.....great detail...
it makes me have a clearer mind for that
Gjb...👍
GREAT VIDEO
one question my running load is around 10 amps and the ct i installed is 100/5 so is it matter that the ct amp is close to the estimated load or inside the max amp range
second every ct S1 terminals need to short/ grounded means the energy meters manufacturer not done this internally
THANK U
1. As far as I remember 10% is the minimum.So if you have 100A CT installed and the load is 10A the CT is still within ist class.Less than 10A load = less accuracy.
2. No.You have to do it.
@@AboutElectricity Hi sir as u recommend to short the S1 terminals on the CT i did the same but when i check the energy meter manual they said S2 terminals need to short.
so at first i did S1 terminals and put on power will it do any damage to the energy meter?
second sir i installed the meter now on 30/5A CT and change the setting on the meter as well for the CT
but when i compare the AMPS measurements between the energy meter and a clamp meter there is around 45 % difference
the clamp meter is showing 1.2 amp on R PHASE and energy meter showing 0.6 amps.
the CT is 30/5A but when i change the CT size in meter to 50 then the measurements between clamp meter and energy meter matches.
energy meter model DIRIS A-20
Kindly give ur valuable suggestion which will clear the problem
THANK U
@@tabasumcarpentry5336 ABID Abid follow socomec manual and earth S2.you will not damage the meter by earthing S1.It will only show 0A in this phase.Set the correct ct value in the meter (30).double check that CT are facing the same side(P1 to power supply).choose correct network from page 14 socomec manual an then program it (page 19).
@@AboutElectricity thankful to u sir.
The cable is entering the CT from P1 side .
The network i set is 4nbl. Three phase 4 wire non balance.
@@MAbid-zt7nm did you managed to solve the problem?
Technical issue with video. There are two terminal "4"'s shown on the power meter in the video. The 2nd terminal 4 should be labelled "6"
👍
@@AboutElectricity the video is a very good video, just thought that terminal might cause a little confusion
@@paddykriton3475 Thank you. Unfortunately I can't edit this video. I would have to delete it and repost it on yt again.
I don't understand why do you need a transformer in here?
Thanks, the “instructions” that come with it are a fucking joke
