Using Zipabox Power Expansion Module with 208Y 3-phase service
Need Answer
I have 208Y 3-phase service. I would like to measure complex power on all 3 legs. Can I do this with the Zipabox Power Expansion Module and 3 current transformers? How many voltage inputs does the module have? Would this require 3 modules or just one? Will the system compute the total instantaneous power correctly for the 3 legs, or just look at each one independently? Are there setup instructions somewhere that give some detail about the Power Expansion module setup for power monitoring?

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 not the zipato module but are also planning to use it for individual 2 phase breakers and keep the existing
