Dear Friends,
I have a 500KVA transformer supplying whole factory having
3 phase and single phase mixed loads. Power room has
ammeters connected via CTs for individual phase. Now I know
that readings shown on meter for each phase say R,Y and B
are line currents. But when I want to know the total on
transformer do I need to add the currents of all three
phases readings shown on meter or value for anyone phase
will give me the correct power load on transformer for that
point of time.
2. If ammeter shows unbalanced readings for R,Y, B phases
say 150, 250 and 300 respectively so can I assume that 150A
i.e average of 3 will be the 3phase load currents and
remaining will be 1phase currents. Please clarify my doubt.

If you wants to know the total load of transformer , you must use a watt metrer , OR you will calculate the load in watts of every individual phase then sum of all three phases will be your answer.
