Dear all,
I am trying to find equation for 3phase 3 wire , 3 phase 4 wire voltage, current, wattage, total power
etc. I have the 3 phase 4 wire device where it can measure voltage and current (using CT out.)
Now i wanted to measure the same for 3 phase 3 wire system.
in first case neutral is common , where i could able to read the voltgae, current, watatge, total power etc.
Now i have removed neutral, since it wont get common closed path it wont calculate the voltage , current, power etc. can someone suggest me how can achieve this using simple common circuit.
Its nothing but Y, Delta reading & calculate value.
End application : 3 phase energy meter with common 3 phase 3 wire & 3 phase 4 wire system
