Power the wattmeter as indicated.

Current transformers

In order to correctly select the current transformers, you should consider the parameters indicated
below:
I : Rated primary current (A)
p
The rated primary current must be more than or equal to the maximum current per phase in the
system.
I : Rated secondary current (A)
s
Value of the rated secondary current of the current transformer.
The rated current of the wattmeter to which the transformer secondary is to be connected is In = 5 A
and the maximum current of the same is Imax = 10 A.
In order to ensure the accuracy of the wattmeter measurement, it will be necessary to use at least one
current transformer with a rated secondary current of Is = 5 A.
For transformers with a rated secondary current of less than 5 A, Ingeteam
does not guarantee the accuracy and correct operation of the SMART DLM.
You must not use a transformer with a rated secondary current of more than
the maximum wattmeter current, in other words 10 A,
