Energy Meter DSB28-3C wrong voltage ?
Under Consideration
Hello , just connected the DSB28-3C Energy meter and had to connect all three voltage leads to the same 10a breaker point l1/l2 since the main 3 phase breaker have 63a and , but i get wrong voltage , 50-80 v should be around 230v? any experience anyone?
I like this idea

I can answer the question myself , the DSB28-3C is ment for a TN cs system and that means it has a neutral wire but my system has a It system and that means it does not have a neutral and is isolated from the transformer supply , that means the voltage readings will be offset from star point 3 phase , but according to math with division of square root of three when all three voltages is added it is correct , the main watt is also correct ,amp on each phase is correct but amp on all phases is not correct . but correct me if i am wrong

this is if all neutral wires is connected to one phase on a it system and voltage readings will be between 100 and 150 vac...
